Started work on new ChainLight.
Ray angles for ChainLight are now interpolated.
ChainLight now translates and rotates with attached body.
Replaced instances of float[] with FloatArray to allow chain vertices to be updated.
Fixed a problem with certain ranges of segment angles (lerp vs slerp). Added ray debug rendering.
Added to ChainLight rayStartOffset, for specifying a gap between chain and beginning of rays.
Added to ChainLight int parameter to specify on which side rays fall (positive: left, negative: right)
Culling and contains(x,y) now work for ChainLight.
Little bit of cleanup. Added some javadoc.
Removed small bottleneck from ChainLight's calc of bounding rect.
Merge pull request #19 from sprucely/master
