MAD description of UMER - Injector

Description of the UMER Injector lattice using the Methodical Accelerator Design (MAD) language. Reflects the repositioning of the SOLENOID in June 2006.
Note that this reflects the use of Santiago's effective hard edge model, so the strengths of quads and solenoid need be divided by some factor (in the magnet table) to get the peak strengths, e.g. for use with the full profile in WARP.  Note also that the strengths quoted are for matching the 23.5 mA beam.  For matched settings for other beams, see the Matching Settings table.

QR2 and QR71 are different

This file does not account for the slight change needed to be done on QR71 and QR2 (166.94 and 164.61 m^-2 for kappa, respectively)
