  1. Add clockwise analysis for GEOS_CAPI 

    Add a `RGeo::Geos::Analysis.ccw?` method which itself uses the
GEOSCoordSeq_isCCW_r to determine if a geometry is counter-clockwise.

Also add an error.h header to help throwing errors when there is an
issue in the c extension. And add a `RGeo::GeosError` for GEOS related
errors.
