Hello!

I have now splitted the SWIG interface into 6 combined modules. 

  common, io, mesh, function, fem, la

The largest .cxx file generated now is 2MB (for la with all linear algebra 
backends installed), instead of 6MB. That is still pretty big and take some 
1GB of memory during compilation. But the interface can now be generated in 
several threads, reducing compile time considerable. The runtime memory print, 
read from a simple top, is not much more than before (some 100MB), which is 
good.

They new compiled modules all resides under:

  dolfin.cpp.foo

All types and functions are now automatically included into:

  dolfin.cpp

which means that most modules under site-packages/dolfin still works fine. 
There are now more types included from the compiled interface by default. If 
this is a problem we can change that. But now everything is automated. No 
handpicking done.

The logic in the new SWIG interface is described in:

  dolfin/swig/README

One thing to be aware of is that any reference to the compiled interface from 
another combined module have to be preluded with the name of the module. 
Example, in la/post.i we call dolfin_error, which is defined in common. Then 
we do:

  common.dolfin_error(...)

instead of previous:

  dolfin_error(...)

Have fun and let the bug reports come raining!
