Message:

Enhanced Chronos for more accurate timekeeping.

• Chronos is now safe to use w.r.t. recursive function calls.
• Chronos now gets const ref of token name in each function.
• TESTFIX: dummyTest() now checks on recursive function.
• Chronos now offers its internal timekeeping via const ref to outside.
• Chronos also now has up to nanoseconds precision when either time.h or sys/time.h is present.
• librt required from clock_gettime().
