I've run some small tests and the UMFPACK wrappers seems to work  
fine.  Well done, Robert!  Well done to Pearu too for his help with  
distutils.

I've added some small unit tests in linsolve/umfpack/tests/ 
test_umfpack2.py, including two that are commented out because I  
can't figure out how to disable umfpack with the useUmfpack  
variable.  Could you please check this, Robert?
