Implemented compilation of C++ expression strings from python.
Documentation will follow later :-)

description:
Several Python assembly optimizations and new options:
The following options are now available:
dolfin_set("optimize form", True) # Use optimization -O2 when
compiling generated code
dolfin_set("optimize use dof map cache", True) # Store dof maps in cache for
reuse
dolfin_set("optimize use tensor cache", True) # Store tensors in cache for
reuse
dolfin_set("optimize", True) # All of the above
Each one of these may make a significant difference for the
speed of assembly from Python, in particular for repeated
assembly.
With these options set, the difference in speed between assembly
in C++ and Python using the JIT compiler is negligible. (For forms
which don't depend on functions that are evaluated in Python.)
