Bump version to 5.1.0, after 5.0.0 release. As per the chosen versioning system, this immediately becomes 5.1.0, the master development stream - hopefully ALWAYS stable - with improvements of all types... Should any bug fix be interesting for 5.0.0 release, this change would be push to the release/5.0.0 branch, making it version 5.0.1... or 5.0.0RC2 if still in the RC stage of release... 2015-07-13 00:08:37 +00:00			`5.1.0`
Rename two headers. Issues #224 #223 #221 But this seemed a good time to release 5.0.0.RC1... 2015-06-30 17:59:00 +00:00			`2015.06.30`
