ENH: FEM refactoring as contracted for ITKv4

This commit makes the FEM framework more ITK like. There is
now a FEMObject to define the finite element problem and
the Solver derives from ProcessObject. Substantially more
testing is performed on this code. Much of this work
was contributed by Kiran Shivanna.

UPD:   All tests now pass except itkFEMC0TriangularElement-Quadratic.
       This result needs to be revied for numerical differences between Solvers
UPD:   Currently disable FEM registration test. This needs to be refoctored
UPD:   Updated regression tests. Removed FEM Registration tests
UPD:   Replaced explicit New() with itkSimpleNewMacro()
UPD:   Added the itkFEMRegistrationFilter and updated tests
UPD:   Fixed a bug in the FEM Registration filter test
UPD:   Added landmarks to regiatration
BUG:   Added Landmark points back into loading
ENH:   Added test data to suite of FEM tools.  Test data added to FEM toolkit
       for supporting new refactored framework.
COMP:  Fix circular dependency issue btw FEM and SpatialObjects
COMP:  Compile errors
COMP:  Commented out Examples to allow building.  Worked with Brad King to
       fix bugs in the DATA{} upload mechanism
ENH:   Decoupled reading of FEM objects.
BUG:   Fixed failing tests and documentation
STYLE: Removed unnecessary files from build tree.
COMP: Rebased to current ITK, to pick up new MetaIO for FEM
COMP: cppcheck static analysis

FEM specific code from SpatialObjects was
extracted to the FEM module, and a generic
registration interface was added to Spatial
Object to allow runtime additions of
supported objects that conform to the
SpatialObject interface.
