The syntax for this function is simplistic. It takes a C++ code block that is 
defined within a dolfin namespace {...}, puts it into a proper SWIG interface 
file, add appropriate declarations, like shared_ptr declarations, and compiles 
the module. It needs documentation. However a simple example could be 
something like:

  compiled_module = compile_extension_module(code,
                     dolfin_import_files=["mesh/SubDomain.h","function/Function.h"])

where code is a C++ code block, and dolfin_import_files are optionals. 
Including them will reduce the compilation time.

I know Garth asked for something like this. It would be nice if you could 
provide some code that I can throw at it.

If nothing comes out of this, I have at least reused alot of code in the 
compile_{functions,subdomains} functions :)
