Detailed Description

template<class T>
class BFieldMesh< T >

A 3-d mesh (axes z,r,phi) representing a simple field map.

The mesh is made up from 'cells' We hold numz, numr , numphi positions defining the corners of the cells.

Then we have numz X numr X numphi field values at these corners

The field type is templated simalar to BFieldVector

It is short for both solenoid and toroid for the nominal case. There is a special case for BFieldSolenoid (not used in the nominal case) which allows a tilt between the nominal and 'tilted' solenoid fields and uses double.
