Detailed Description

Class DeriVector2 holds a vector value and its derivative on the parameter that the derivatives are being calculated for now.

x,y is the actual vector (v). dx,dy is a derivative of the vector by a parameter (dv/dp). The easiest way to fill the vector in is by passing a point and a derivative parameter pointer to its constructor. x,y are read from the pointers in Point, and dx,dy are set to either 0 or 1 depending on what pointers of Point match the supplied pointer. The derivatives can be set manually as well. The class also provides a bunch of methods to do math on it (and derivatives are calculated implicitly).
