FFEA no longer passes tests if the system's default version of Python is 3.x

[Robert Welch]

You can remedy this by specifying that -DPYTHON_EXECUTABLE is a python 2.7 binary. The rest of FFEA will still just use whatever the first version is on the $PATH. A longer-term solution would be to make FFEA require 2.7 (or upgrade it to 3, of course).

I think the software will need upgrading to Python3 with 2 reaching end of life, otherwise, it will just cause problems at a later date. Will likely be my job to do so.

This 2.7 requirement should be reflected in the documentation, instead of providing a minimum Python version. Sarah and I are planning on going through it at some stage.
