Still a work-in-progress.  Committing to get around some issues in Eclipse with a corrupted index.  Removed Subversion $Id$ keywords.  Added current working directory.
Another intermediate check-in to ensure that nothing is lost prior to synchronizing with GitHub.  This commit does not compile.
Scala worksheets in Eclipse will now be ignored by default.  If required, they can be added manually, and will be treated as regular text files.
Corrected links in release notes.  Improved content of GitHub repository
READEM.md file.
Corrected some typos in the GitHub repository README.md file.
Complete work on utils files (with detailed Version implementation being put back to a future commit - current state simplified to address more pressing objectives).  Also updated Scalastyle to latest 0.2.0 release, and re-introduced file header checking.
Extensive changes to physical quantity measurement code.  Updated copyright messages to reflect change of year to 2013.
Temporary commit.
Add macros for common assertions.  Switched from Maven to SBT in order to compile macro code successfully.  Resurrected the AutoMod Cell 3D file import code.  Significant changes to measurement classes.  Numerous other modifications.
Implemented CellAttributes interface in Cell class. Fixed requireValid macro & associated common test method. Added LineWidth implementation & tests. Updated CellColor, LineStyle & DisplayStyle enumerations & tests to report valid minimum & maximum values. Some minor other import fixes.
Refactored reading of the CellColor, DisplayStyle, LineStyle & LineWidth classes. Added basic JointType class and updated Joint classes.
Added JointData class. Added readBool method to CellScene class. Refactored BoundingBox read into a separate class.  Refactored CellFlags read into CellFlags.
Passed cell flags through to Joint Constructor. This is because joint geometry data is only present if cell flag bit 2 is set, and the format of that data depends upon cell flag bit 3.
Added ability for a transformation to read translation data from the cell data stream.
Improved mechanism by which BoundingBox reports affected axes in the event of problem reading data.
Added some detail for Rotations and Rotation Order.
Switched from Java3D (which is dead and buried) to ScalaFX 8 (which has yet to be born).  Also added some extra transformation work.
Added ability of sets to read children from data stream. Updated Scala compiler options during builds.
Added reference to Set element documentation on web-site.
Removed some redundant cruft. Added some rudimentary 3D mesh generation for Trapezoid (with infrastructure for other similar objects). Added ability for Sets to create associated ScalaFX scene Nodes.
