Renamed to fit Boost's directory naming
Fixed up include paths
Missed a path change in scons config.

Updated Readme to show travis CI and coveralls for boost.afio not triplegit.
Turns out there was another scons path fix.
Actually tested it on Linux this time. Now it compiles.
Maybe the coveralls API token for triplegit was confusing coveralls? Disabled now.
Merge pull request #2 from BoostGSoC/import_geometry_boostbook

Changed directory paths to match Boost's such that docs machinery can find things.
