description:
A clean up in assemble.py
- Putted code for extracting coeffisients in own function
- Added the parameter "form compiler", which can be set by, e.g.,
dolfin_set("form compiler","ffc")
- Dolfin assume that the form compiler implements the jit function, which takes
a form as first argument and an optional option parameter as second argument.
- The options parameter is optional. If provided it must be a dict that is
handed directly to the registered form compilers jit function.
- Added a private function _jit(form, options) which uses the jit compiler
that is provided by the module, registered in dolfin_get("form compiler").
- This commit requires that also ffc is updated to newest version, as the jit
interface needed to be updated.

description:
Implemented x.array() and A.array() for GenericVector and GenericMatrix in PyDOLFIN,
both returning a numpy array with a copy of the data. (NB! dense matrix!).
Try f.ex.:
In [7]: A = assemble(u*v*dx, mesh)
In [8]: B = A.array()
In [12]: import scipy.linalg
In [13]: scipy.linalg.eigvals(B)
Out[13]:
array([ 0.08803702+0.j, 0.05652695+0.j, 0.05015566+0.j, 0.06728417+0.j,
0.01369043+0.j, 0.01388889+0.j, 0.00755545+0.j, 0.02386164+0.j,
0.02406092+0.j, 0.02966277+0.j, 0.01663435+0.j, 0.00759757+0.j,
0.03219184+0.j, 0.02969543+0.j, 0.02255606+0.j, 0.01660086+0.j])
