MAD description of UMER - Ring

Description of the UMER ring lattice using the Methodical Accelerator Design (MAD) language. Reflects the change of all the ring quads to the new type (3rd generation) week of 8/16/2006.
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.

! Focusing quads (-ve for electrons)
NQF: QUADRUPOLE,L=0.05164,K1=-161.02
