Finally got the order of the printing of the counters done.

On the output file "Salida.txt", the amount of tokens are written in the
next order: Identifier, Integer, Float, String, Sum Operator, Product Operator,
Assignment, Relational Operator, Logic Operator, Left Parenthesis, Right
Parenthesis, Left Curly Bracket, Right Curly Bracket and Delimiters (,|;).

Also fixed a slight bug that prevented operators < and > to be properly
identified.
