Add a SAL grid generator, using the depth first search walker.  It currently
just generates simple IF statements for each condition, nest IF statements as
appropriate.

To avoid duplication between the EventB and SAL generator, rename the EventB walker
to a more general name.  Also introduce a special interface, to ensure a depth
first walker is never used against a breadth first generator, and vice versa.

Add support to actually declare variables.  Currently only the real and
booleans are supported.

Intial work on SAL code generation.  For now, just deal with Real and Boolean expressions.

By default, all Simulink enumerated values are formed as: enumerationtype.constant
The current MATLAB parser in jTET fails to recognize this.  Fix this so that
it recognizes these constants properly.  Also add a test to verify this mode.
Note that the original style of just the constant is still ok, thought in
a TET block that style may not work.

Variable types now follow variable names in terms of naming rules.  This
relaxes them to allow numbers in the name.

The file name that was used in the refinement relation tag was being
incorrectly generated as tablenameMi, where tablename was the tablename,
and i was the refinement layer.  However, the actual files were called
tablename_Mi.  Fix this by using the same function to generate the name,
and standardize on the tablename_Mi notation.

From this version, two kinds of mode, i.e., Single Output No Refinement
(SONR),Single Output With Refinement(SOWR) are supported.

Seperate the creation of project and generation of table xml files. So
that in the future we can support multiple tables in a project easily.

The JUnit paramerized class is used here instead of using a massive
class repeating the various setup/test procedures.

Combine the several parameters in the constructor to one table object
parameter to make the interface more clean.

Make sure all closeable objects in EventBFileWriter are properly closed,
even in the presence of exceptions.

This new table name property is added when generating EventB files, but
can be used for other purpose too.

maven-assembly-plugin: 2.4 -> 2.4.1, bug fixes mostly.

Since jTET is now getting preped for deployment to Maven Central, update the
POM file, adding various metadata tags.

Update some out of date dependencies.  All test still pass, so everything
should be fine.

Underscores are fine characters for names.  Allow their use as well.  This is
just a change in the lexer, which wouldn't recognize them.

To ensure better test coverage, add boolean and predicate subtypes to the list
of generic tests.  Both are again very simple additions, and all current
generators are fine with them.  They are skippable in the usual way.

At least for the SAL generator for SimCheck, I need to transform the variable
names.  Thus add the ability for Variables to have different names outputed
during generation.  This ensures that a given variable always has its name
match as expected.

Also update the various tests to exercise this new functionality.

jTET needs a large amount of throw away instances of types or their marker
for its work.  Instead of creating a new instance each time, use a static
instance to avoid the work.  It also makes it more obvious when something is
temporary.

In the previous version, output value is set to begin with 0 and increase by 1 each column, like 0,1,2,3...
Now the output value is really aquired from its corresponding cells.

Until now we have test cases for one layer table, two layers table, three layerstable and one Simple Insulin Infusion Pump (IIP) table.

For now, only single output single grid tables are supported, and only with simple one operator expressions.
Each row in the conditions grid corresponds a single event in EventB, with each cell in the row corresponding to a guard for the event.

A missing throw keyword allowed an exceptional circumstance to continue, when
an enumeration name conflicted with either another enumeration name or with
a variable.  Add appropriate tests to catch such issues and add the throw
keyword.

Make the input and output variable list have more useful names.  Before, they
carried either a legacy idea of what they might have been, or just generic and
confusing.

Add an initial table description to hold what a table is.  Currently I'm not
sure if it is best, as it limits tables to 2 dimensions, and allows for multiple
variable 2 dimensional tables.  But for now it fully represents MATLAB's TET
tables (though TET can't represent all tables represented here ...).

When dealing with a hierarchical grid, it is useful to know how many cases
there are.  Add a simple function to do so.  Also add some quick unit tests
to ensure it functions.

Ignore IDE and generated files in this repository.  This file is recreated
here as the ignore rules used to be in the root .gitignore.

As discussed, do the package rename now.  All MATLAB code is adjusted as necessary,
all java tests pass, and the quadratic example continues to typecheck, as
expected.

As discussed, rename Matlab2SMT to jTET.  Matlab2SMT is a bad name for the
java project, and with its imminent removal first rename it to avoid breakage
in MATLAB code.

Matlab2SMT is moving towards being a real library.  Thus delete the useless
App class that makes it look like a library.  Its only useful function can
be done manually anyways.

To comply with MATLAB Central's license policy, change all files to be BSD
licenced.  Also add a LICENCE file to the root of the project folder, to
make it more obvious the code is 3 clause BSD.  The Licence text is copied
from MATLAB Central.

Add a 2d grid to the java code.  It uses List<> to make the 2d grid itself,
but hides all implementation details, to allow for future modifications.

Update antlr4 version to 4.2.2, and apache commons to 3.3.2.  Also fully
specify all plugin versions.  While the latest should be used by maven,
experience shows this is always the case.  Thus verify everything.

Due to how the matlab grammar was setup, things would break horribly on systems
with case sensitive file names.  This occurred as some elements had names
differing only by case, which both Antlr and Java were fine with, but relied
on the system have case insensitive file names.  Mac/Windows would thus break
in most cases, along with Dropbox.

Fix by removing these names.  I don't use them, and the one useful case is
handled differently, which shouldn't cause issues in the future.

Make sure enumerated types are only emitted once, even when there is more
then one variable declared with the type.  Also fix the generators so they
actually ensure this.

Also, CVC3Generator got some cleanup around the relevant code.

There is no reason to use a HashMap in the test, which makes checking the
result harder.  So, instead just use a LinkedHashMap so the result is always
the same.

Since variable subtypes can depend upon previously declared variables, emit
the variables in the same order as defined.  While some languages may not care,
it is better to be safe then sorry.

Also, since variables are now always emitted in defined order, remove some
excess try .. catch blocks, which were attempting to handle the unknown order.

Add support to SMTLIB and CVC3 to generate enumeration types.
