[phobos] Proposal of StopWatch module

[Steve Schveighoffer]

in anticipation of what might happen...

Tango does have a StopWatch object, it looks like this (API only):

void start()
Start the timer
double stop()
Stop the timer and return elapsed duration since start()
ulong microsec()
Return elapsed time since the last start() as microseconds
static this()
Setup timing information for later use
ulong timer() [private, static]
Return the current time as an IntervalI hate to do this, but I don't want to 
incur any more issues from the Tango team.  Have you looked at this tango module 
before writing your StopWatch object (note the StopWatch module is separate from 
the other tango modules)?
