Fenics

------------------

- Add support for FErari optimizations, new flag -O

------------------

- Remove verbose output: silence means success
- Generate empty boundary integral eval() to please Intel C++ compiler
- New classes TestFunction and TrialFunction

------------------

- Work on manual, document command-line and user-interfaces
- Name change: u --> U
- Add compilation of elements without form
- Add generation of FiniteElementSpec in DOLFIN formats
- Fix bugs in raw and XML formats
- Fix bug in LaTeX format
- Fix path and predefine tokens to enable import in .form file
- Report number of entries in reference tensor during compilation

------------------

- Add demo Stabilization.form
- Further speedup computation of reference tensor (use ufunc Numeric.add)

------------------

- Report time taken to compute reference tensor
- Restructure computation of reference tensor to use less memory.
As a side effect, the speed has also been improved.
- Update for DOLFIN name change node --> vertex
- Update finite element interface for DOLFIN
- Check for FIAT bug in discontinuous vector Lagrange elements
- Fix signatures for vector-valued elements

------------------

- New fast Numeric/BLAS based algorithm for computing reference tensor
- Bug fix: reassign indices for complete subexpressions
- Bug fix: operator Function * Integral
- Check tensor notation for completeness
- Bug fix: mixed elements with more than two function spaces
- Don't declare unused coefficients (or gcc will complain)
