uPPPP name

[dwerner95]

There is a lot confusion going on whether the name should be uPPPP or uPPP or what else. The name of the framework will be Universal Post-Processor for Particulate Processes, hence 4 Ps make sense. however that is a bit much to type in python. (e.g import upppp) Hence I propose "up4" or, which sounds even better "up3" (Universal Post-Processor for Particulate Processes)

Please let me know what your thoughts about that !

Personally I think that up4 sounds the best; then you are not removing the last P (processes).

It is slightly easier for my non-native tongue to pronounce "up4" (as in "up-four", rather than spelling "U"-"P"-"four") - so I'm voting for "up4" in both the Rust and Python libraries.

It is also short enough to not need aliases like"import upppp as up".

Yeah I agree with Jack
