Profiler

public class Profiler extends Object
A easy-to-use class that wraps one global ProfilerImpl object. Use it to begin and end profiling in one 'profiling thread'. I.e. use this object to get timing for sub-operations. Use separate ProfilerImpl objects to get timings for overlapping profile needs.

WARNING: Call reset at the end to avoid memory leaks.
