Compiles invalid cpp code when using non-existing variable name

[havahol]

Stumbled upon the following bug. Writing Equelle code

Output("max of u", MaxReduce(u))

when no variable u has been declared, produce the following c++ code

er.output("max of u", er.maxReduce());

which gives a C++ compile time error (maxReduce needs a CollOfScalar parameter). Equelle compiler should notice that we use an undeclared variable.

Thanks for noticing. Currently function call arguments are not checked, which is a significant lack. I consider this a high-priority bug.
