A lot of old files from old documentation systems etc. is in package.
These are now removed or moved. Old notebooks are in docs/tutorials.
This PR closes issue #124.
force vector, autodiff takes care of linearization
- elasticity equations are now solved using e.g. principle of minimum
potential energy. syntax is quite good, see notebook.
- updated how to interpolate fields, by introducing function spaces.
syntax is now good. still have to figure out how to do time derivatives
- etc. etc. tutorial is broken at the moment, i took of get_lhs and
get_rhs because they didn't really work.
