//
//
// A class for control of the Magnetic Field of the detector.
// The field is assumed to be uniform.
//
// Should this be a:
// i) messenger
// ii) user class that creates the field ?
// iii) simply a derived class of Uniform field ? <== I have chosen this now.
// iv) a field manager that creates/updates field (Prefered?)
