All python 2.7 support will be dropped after this version, except for essential bugfixes.

If you need future features please use Python 3.

- Dropped all support for python 2.7
- Swapped the mutable and immutable defaults
- Removed the inclusion of the constants at the top level
- Removed all mutable timestamps

Added extend_to_encompass_timerange function for immutable.TimeRange.
Hardcode use of python3.4 in RPM spec file to workaround missing python3 soft link in recent (>3.4.9) centos python34 RPM.
