Renaming of analyses

[hartogss]

Similar clang-tidy, it might be better to make the analyses simpler and later use the extracted features and statistics to combine interesting data to gain insights.
E.g. instead of improving ALA to find uses of algorithms in both callexpressions and function pointer, maybe it would be better to rename ALA to std-algorithms-call-exprs and write a second analysis called std-algorithms-functions-pointers.
I reckon that this would greatly aid in keeping the analyses written more simple and more clear.
Right now, one has to really study the doc to understand what ALA really does, which is hard to do and hard to maintain.
