Usage of this class is intended to measure the time spent during a function execution

To use it you just need to make the target class inherit from this one.
Result will be printed output indicating whether a call to a function started and finished.
When a function ends the output will also contain the execution duration in the format of:
Minutes:Seconds.Microseconds
The --> Begin and --> End forman can be used format the log nesting it for better understanding.
