CX version 0.1.2

This release has a number of minor bugfixes and new features. This release also provides experimental support for openFrameworks version 0.9.0, which is currently in the release candidate stage.

The main changes:

• There is now a brief FAQ in the manual.
• In the CX::Algo namespace, there is a new version of the fullyCross function that returns a CX_DataFrame rather than a vector of vectors, which makes it easier to work with.
• In the CX::Draw namespace, getBezierVertices is a new function that calculates the vertices of a bezier curve given a vector of control points and the time points at which to get the bezier curve.
• CX_LapTimer and CX_SegmentProfiler can now be named and print their names with the sample statistics. This makes it easier to use multiple profilers in your code.
• The unit converters in CX_UnitConversion.h/cpp now take vector-valued arguments.
• There is now a writeKeyValueFile to go along with readKeyValueFile.
• CX::Util::unique used to assume that the argument was already sorted and would return non-unique results. This has been fixed.
• Some other minor bugfixes.
