This is a wrapper for the other FindMatLL method that returns density, A, and Z. It is here to make easy comparisons between the LL and table methods.

int DRootGeom::ReadMap ( string  namepath,
int32_t  runnumber 
)

Read the magnetic field map in from the calibration database. This will read in the map and figure out the number of grid points in each direction (x,y, and z) and the range in each. The gradiant of the field is calculated for all but the most exterior points and saved to use in later calls to GetField(...).
