I updated the AHDC hit process to use the latest form of the T2D function for the drift chamber. Along with this, the correct constants are loaded from the ccdb, and the function is numerically inverted and interpolated to find the correct distance when supplied with a time.
A couple notes: the T2D function is forced to always have a positive slope to ensure a valid inversion function. Also, interpolation routines have been added to calculate distance between the nodes in the numerical inversion grid.
