public class StaticCounter
extends HashMap

This class is an utility to create a set of counters. Using the static method getCounter("name") it is possible to obtain a specific counter or create it if it does not exist.
Every counter can have multiple key-value combinations as it is a HashMap. It is necessary to use the count(key) to increment a value of a counter, and use reset(key) to reset a value of a counter.
This method are synchronized to limit possible use to one thread at a time.
