New measurement of ASP congestion, separately from adjusted congestion
and pushed by EdgeNetwork.  More accurate.
Added information on # of network flows sent and received to data output
analysis script and display html
Added direct measurement of quality, alternate measurement for # of
flows sent and received.
Added information on total population to BackbonePurchaseStimulus
DataCenter (originators) and EdgeNetworks (sinks) now update total flows
sent separately from bandwidth averages.
Added ASP quality graph generation and to html file; fixed bug with # of
netflows display (graph was looking at wrong variable, bandwidth)
Implementation of LinearASPIndividual.  Sets prices, quality, and amount
of NSP bandwidth purchased based on a linear equation where genome
values are coefficients on terms comprised of stimulus variables.
