Adding first pass of dragonfly custom model: routings (adaptive, progressive adaptive, minimal, non-minimal) should be functional with DF traces, need to update for making optimistic mode functional

- Stats are output to log file in modelnet-test directory
- Stats are added from terminal_final(), switch_final(), report_stats(),
and within main() of the synthetic workload file
- Stats include ROSS sim metrics (i.e. synch mode, gvt-interval,
rollbacks, etc.), as well as network params/results (i.e. num terminals,
num switches, workload, avg latency, max latency, etc)

Fat Tree model finally compilesgit add src/networks/model-net/fattree.c codes/net/fattree.h ! Hooray./gephi/bin/gephi Many changes/updates have been made. Guarenteed to have bugs.

Added msg_start_time to fattree.h. Appended fattree to the begining of the terminal_magic_num variable name. Updated packet_event()
