Version 0.1.3:

- variable declarations:
	for identifiers with assignment (int i = 1;).
	for identifiers without assignment (int i;).
	(auto assign to 0 for ints , false for bools)
	
- assignment for a non-declared variable does nothing.
		
- toString() methods for statements.
		
- Inc/Dec for identifiers (i++; , i--;).
