getValues

public float[] getValues(double[] x,
 double[] y,
 int numPoints)

returns a double array of values that are located at points x,y. Values in the array are in the same order as the input x,y arrays. the x and y values are assumed to be in the same coordinate space as the data. I.E. the x/y values are offsets from the UL and UR and which is assumed to be (0,0)
