Re-organization: moving all files. I re-organized into original cpp directory and 4 additional directories: base, geometry, slam, and tests. cpp will be further renamed/sub-divided and contains the core library. I wanted it not depend on geometry or slam, which necessitated moving complicated tests to a dedicated directory.

Moved the subdirectories that compile into libgtsam.la into a 'gtsam' subdirectory. Hopefully a good fix for the problem we had trying to make a gtsam distribution, that the source directory may not be called 'gtsam'.

// create expected Chordal bayes Net
Change that may be reverted again soon - templated factor base type on key and make IndexFactor and IndexConditional for all current code. Did this to experiment with using symbols on the linear side in an efficient way but am putting this on hold for now because of complications. Will revisit and either fix or revert to int-only later in the week. Also moved some files to experimental and templating EliminationTree on FACTOR instead of FACTORGRAPH.
