Too many branches

[ye-luo]

A year ago 10 branches, now 28. This is a development process (human) bug.

We should adopt best development practices.
Every developer needs to use a fork and work under their fork.
If a feature is ready and well tested, it needs a pull request and a proper code review before merging.
The master must be protected such that no one can push directly.
A not merged feature basically doesn't exist so once done, must be merged or dropped in the developer fork.

This is the workflow we use for QMCPACK development. Hopefully it is helpful to you as well.
