This is a simple hair simulation, done using mass-springs and RK4 integration.
Simply the run the program and eveything should either be intuitive or explained by the UI.
Things you can change that the UI doesn't include:
Amount follow hairs are spread out from the guides: In NGLScene.cpp -> initialGL, change the HI and LO variables in the create hair section, they should be 2 values that are slightly more or less than 1
Simpler collisions with scalp: In GuideHair.cpp -> updateJoints, change complexCollision to simpleCollision
How far off the scalp hairs rest: In GuideHair.cpp -> updateJoints scalp penetration section, change .05 to something else
