- save previous cumulative time values rather than actually reversing
  calculation in order to avoid minor discrepancies introduced by
  rounding error

- not producing correct results yet

- also tweak temporary hard-coded network parameters in loggp method to
  look somewhat like Tukey IB network for quick sanity checking of
  output

also misc update to how loggp method plugs into modelnet

- just a copy of simplenet with variables and functions renamed for now

Adding statistics collection using lp-io in model-net API (comes from the simple-net stats collection), works for simple-net, torus and the dragonfly network models

Updates to modelnet (1) Updated the mapping configuration for dragonfly (the mapping now distributes the routers equally on all the PES.  The old dragonly mapping configuration was placing the routers on a single PE which was causing congestion on that PE leading to slow model performance in parallel ) (2) Updated 'make check' to handle dragonfly and torus test cases as well (3) Remove the num_servers argument from model-net test case, the number of servers are now calculated from the config file (4) Placing the ross mapping parameters in the codes mapping file

Adding dragonfly network model with codes, model-net-test case run time parameters are updated (see README_MN_TEST.txt for details)

Adding dragonfly network model with codes, model-net-test case run time parameters are updated (see README_MN_TEST.txt for details)

Updates to modelnet torus plugin: reporting torus average+maximum latency and hops traversed via model-net API function

Adding the torus network plugin with modelnet API, see model-net/README_MN_TEST.txt for instructions to run the test

Adding the torus network plugin with modelnet API, see model-net/README_MN_TEST.txt for instructions to run the test

Updates to model-net test program based on the new config file format. We can now configure all network parameters from the config file

Adding back the simplenet magic check (it works fine for the case where there the modelnet and server LPs are on the same PE)
