Fixed external jar build path
Use constant in log2 and add implementation note to findMSB
Merge branch 'master' of seymour.lyricsemiconductor.com:LyricLabsADI/dimple
Added links to javadoc for some external libraries
Fixed option conditionals so that no arguments builds both user doc and developer doc and different combinations of switches do the right things. Also changed clean to remove generated files in subdirectories.
Add RealJoint and Complex support to Gibbs solver

Temporarily add a single complex factor-function CSum.  Next is to work on a more complete set.  Renamed ComplexVar in MATLAB to Complex (maintaining the old one for backward compatibility only).
updating java documentation
Merge branch 'master' of seymour.lyricsemiconductor.com:LyricLabsADI/dimple
updated doc
updated doc up through variables API
finished doc on variables
Added a bunch of Complex factor functions, including overloaded operators, and got vectors of Complex factor functions working
Merge branch 'refs/heads/master' into GibbsRealJoint
updated factors
Fix multi-dimensional real-joint variables and add test (for complex case only)
Fix test to account for RealJoint now following the MATLAB convention where array dimensions N implies an NxN matrix (like all other variable types)
updated some doc
For Built-in complex factors and operators, allow mixing complex and real variables
Remove old ComplexVar class
added more java doc
