libmeminfo: librank optimization using maps instead of vectors
librank was calling std::vector::find_if in nested loops when iterating
through processes and maps.
Changed the implementation to use std::map::insert, this resulted in
a significant improvement to execution speed.
Test: time librank on crosshatch
Before: 1m22.57s real 1m15.87s user 0m05.79s system
After: 0m03.85s real 0m00.88s user 0m02.92s system
