Added PAPIInst library for LoopIntercept tool
added comments and usage example at the beginning of PAPIInst.cpp
First version of FrequencyConfig. This version still uses the external daemon (which will be removed) and has a potential error for using IPC for clock modulation.
removed daemon and added ips in modulation
Fixed modulation with IPS. Moved MPI rank initialization; added detection of frequencies and granularity in modulaiton
the definition of MYCPU was commented out
