description:
Fixed variables being duplicated on stacks in split_by_dependencies.

Added ufl-script-params.py using optparse, to be used to
merge scripts like ufl-analyse, ufl2latex etc. into one,
with more flexible usage options.

Added some local sandbox test files (nothing to see).

description:
Fixed redundant Variable insertions in split_by_dependencies.
Looking at the output of "ufl2pdf -c hyperelasticity1d.ufl",
it seems like no redundant variables are created anymore
(i.e. there are no variables like "s_51 = s_2" created).

description:
- Fixed some unneccessary Variable insertions in mark_duplications.

- Added quick attempt at rendering UFL expression graphs
  using the DOT graph visualization language. Needs some
  fixing up to look good, but basics work fine. Also needs
  a commandline utility.
