This calculates the magnetic field at an arbitrary point in space using the field map read from the calibaration database. It interpolates between grid points using the gradient values calculated in ReadMap (called from the constructor).

Implements DMagneticFieldMap.

int DMagneticFieldMapCalibDB::ReadMap ( string  namepath,

string  context = "" 
)

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(...).
