Detailed Description

Creates different types of line graphs for detailed output files.

It can produce absolute and relative graphs of density, basal area, or volume for saplings, adults, and snags; and absolute and relative graphs of density alone for seedlings.

This chart is different from other charts in that it displays data from all timesteps at once, instead of one timestep at a time. Thus, it tends to ignore normal chart drawing requests and has its own code to force parsing of all timestep files in a detailed output package at once.

Technically, density data could be extracted from any tree data member, since counting up the total is all that is required. I didn't do it that way because I'm a little lazy, and I'll wait for a hue and cry from the users before unnecessarily complicating my code.
