- Switch to double precision

- Allow accessing entities by GlobalId
- Some more support for writing back IFC
- Prefix EXPRESS Enum values to avoid collisions
- Fix a bug in the SenseAgreement of Cartesian trimmed curves
- Use straight line segment in case point projection failed on trimmed curve
- Add epsilon to polylines and -loops point equality test
- Decompose a convex polygonal bounded halfspace into several unbounded halfspace and process only if they operate on a volume larger than some epsilon
- No longer fail connected facesets if a single face is invalid
- Updated IfcBlender for compatibility with Blender 2.62
- Added additional test files
