Remove package pymad

- remove the common abstract base classes for the pymad implementations
- move TfsTable, TfsSummary to cpymad and jpymad packages (duplicate)
Remove eclipse .settings file

This shouldn't be part of the repository.
Remove cern.madx module

The module was there for backward compatibility, but some things changed
and further will change, so let's just do it the new way now:

    >>> from cern.cpymad.madx import Madx
Remove pymad tests

- the abstract base class (Interface) is not used anymore
- the tfs test was no real test anyway
