Hi Graeme,

I can provide a more concrete list after the Phenix release, but generally,
the migration to Python 3 in 2020 (exact date for Python 2 end-of-life is
unclear, https://www.python.org/dev/peps/pep-0373/) will require checking
through the existing codebase, so we would like to clean things up by
removing unused code and consolidating any duplicate functionality.

I would also like to introduce a more standard template for programs so
that the non-science stuff is more consistent among all programs. For
example, file I/O (with more automatic handling of compressed files) can be
isolated at the beginning with proper sanity checks on the data.
Command-line flags, like an option for showing citations for the algorithms
in the program, can also be more standardized.

The standard program template will also help in migrating the GUI away from
wxPython. The replacement package for the GUI will most likely be PyQt5.

To help track progress and keep everyone up to date, we can use the
"Projects" feature on GitHub.
