Init() public method

Initializes the solver

public Init ( int _Dimension, int _ParametersCount, int _MaxIterations ) : void
_Dimension	int	Size of the dataset to solve against (i.e. amount of data points to fit against)
_ParametersCount	int	Size of the vector to solve for (i.e. amount of unknowns to fit)
_MaxIterations	int	Maximum amount of iterations to perform (20 iters significantly increases error vs. 100, a standard value is 45)
