Pip installation on ubuntu does not come with umfpack #48

Pip installation on ubuntu does not come with umfpack

This seems to be by design, the PIP version of NGSolve has MKL enabled which provides PARDISO, preferred over UMFPACK. The most recent commit enables checking of ngsolve.config.USE_* booleans to avoid this issue and has been tested with the PIP version of NGSolve.

I do not think this is an NGSolve issue, suggest that this issue be closed.

The issue is that different installation methods provide different capabilities. This is A) not expected, and B) not documented ahead of time as far as I know.
