Creation - Elements of the call
An EXPRession is a sentence which can be applied to the content of an FMAT or an FVEC. It can be created in an FTM.object (class expr) or in an FTM.message. In both case, it shares the same syntax:
1_ it is surrounded by simple quotes ' '
2_ it is then encapsulated within parenthesis (to be executed like all of FTM's code)
For instance, the expression returning the value 1 is
'(1)'
