avoid confusion and suppressed .py.in files
Merge branch 'master' of https://github.com/acbauer/CatalystExampleCode
Adding a sample Cinema script.

This requires a verion of ParaView after commit f64ee7a41.
This is after the PV 4.2 release candidate 1.
Updates for PV 4.2 and finalizing the Fortran Poisson example.
Fixing how Dolfin finds ParaView.

The previous version assumed that Dolfin was working with an
installed version of ParaView that had development files installed.
These changes allow Dolfin to work with either an installed location
of ParaView or the build tree location of ParaView. Also fixed the
velocity specification in the adaptor. VTK's format for vectors
is opposite of Dolfins.
Merge branch 'dolfin' into PV4.2_tutorial_examples
