Discriminators

Go through each discriminator describing what it is and why it is used then have links to the performance area plots. Bring those plot pages up as separate windows.

For each discrim plot what value it gets for each ptype (gamma, chhad, neuhad, gamfrag, hadfrag). Maybe also show for 0-4 GeV and 4-50 GeV. Also show for barrel and endcap separately.
