ScalES-PPM

We recently decided to call the ScalES Library "ScalES-Lib". I think we also need to reconsider our choice of name prefix, currently the prefix "ppm_" is used - this does not fit anymore. In my opinion, the purpose of the prefix is global namespace separation and visibility of our work. For practical purposes, the prefix should neither be too long nor too difficult to type or memorize.

Looking at the term "Scales-Lib", several possibilities come to my mind:

scl_
sesl_
slib_
scali_

I don't think this list is already comprehensive enough to start a vote, so I opened this issue in order to have a place for us for further suggestions.
