More methods added to support local and global estimate. If more than one argument is passed through command line, the program creates objects and store their values. The goal is to be able to set speeds on a map, and compare different path speeds between each other, setting a maximum and minimum globals and locals.
Added new function and global variables (because functions may use it). Adding support for local and global values. This will be used in case more than one file is passed as argument for the program. New variables were created. Now a global estimate is possible comparing between command line arguments.
Interessante o uso do 'use subs qw ( <nome das funcoes> ) para declarar funcoes que sao usadas sem os parentesis.
