New Revision: 58836
URL: http://svn.boost.org/trac/boost/changeset/58836

Log:
Boost.Chrono: Version 0.3.0, Doc update for stopwatch feature
    * independent cpu clocks for real, user, system process CPU time.
    * new Stopwatch concept measuring elapsed time between different points in time associated to the operations start, stop, suspend and resume.
    * stopwatch is a model Stopwatch measuring the elapsed time between the start and the stop operations.
    * stopwatch_accumulator is a model Stopwatch allowing to accumulate several time samples and give the average, ...
    * scoped helper classes allowing to pairwise start/stop operations, suspend/resume and resume/suspend a Stopwatch.
    * new Stopwatch Formatter concept
    * stopwatch_reporter is a generic class reporting elapsed time for the Stopwatch concept.
    * process_times.hpp has been deprecated, see process_clocks.hpp, process_stopwhatches.hpp and process_stopwhatches_reporter.hpp.
    * timer.hpp has been deprecated, see stopwatch.
