description:
Marked all occurrences of symbol creation with XXX,
do not use this mark for anything else now.
This is just a step to get overview of the work involved
with introducing a python-based symbol factory.
70 lines contain XXX now, contrasted to almost 600
containing the word 'symbol'.

Also scetched a way to optimize symbolic integration
for matrices where several integrands are equal, but
this is not a high priority and needs benchmarking.

description:
Some optimizations in split_tokens and substitute_tokens, keeping auto_tokens list
instead of appending to local_tokens, this reduces memory usage and copying.
Doesn't seem to help a lot in the big picture, but it's noticable in some cases.
