%% matlab_to_cvc_syntax_translation
%translate matlab syntax to cvc syntax,
% will be added to in the future
% will only work for functions in the prelude
%
% inputs:
%   object:cvc_checker - cvc_checker object
%   matlab_string:string - string to be converted from matlab
%       syntax to cvc
% outputs;
%   cvc_string:string - string converted to cvc syntax.
