Modified the cache hierarchy, reorganized code to eliminate code replication, implemented write allocate / write back policies in L2 cache, added configurable parameters in gpgpusim.config ("W" = Write Allocate, "N" = No write allocate -> "P" = Private, "S" = shared), modified the cache configuration lines to always be separated by ":" instead of ":" and ",", and modified L1 and L2 data cache to be "Write Back" caches instead of "Read Only".

Still need to implement Ahmed's sectored cache implementation.
