Ffc

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

- 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)

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

- Add command-line argument -v / --version
- Add new operator mean() for projection onto piecewise constants
- Add support for projections
- Bug fix for higher order mixed elements: declaration of edge/face_ordering
- Generate code for sub elements of mixed elements
- Add new test form: TensorWeighteLaplacian
- Add new test form: EnergyNorm
- Fix bugs in mult() and vec() (skavhaug)
- Reset correct entries of G for interior in BLAS mode
- Only assign to entries of G that meet nonzero entries of A in BLAS mode

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

- Only generate declarations that are needed according to format
- Check for missing options and add missing default options
- Simplify usage of FFC as Python module: from ffc import *
- Fix bug in division with constants
- Generate output for BLAS (with option -f blas)
- Add new XML output format
- Remove command-line option --license (collect in compiler options -f)
- Modify demo Mass.form to use 3:rd order Lagrange on tets
- Fix bug in dofmap() for equal order mixed elements
- Add compiler option -d debuglevel
- Fix Python Numeric bug: vdot --> dot

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

- Generate function vertexeval() for evaluation at vertices
- Add support for arbitrary mixed elements
- Add man page
- Work on manual, chapters on form language, quickstart and installation
- Handle exceptions gracefully in command-line interface
- Use new template fenicsmanual.cls for manual
- Add new operators grad, div, rot (curl), D, rank, trace, dot, cross
- Factorize common reference tensors from terms with equal signatures
- Collect small building blocks for form algebra in common module tokens.py
