Subject: PMC and IMC locked again, some MEDM maintenance 

a useful piece of code that we should ask one of this summer's SURFs to write:

  1. read in a BURT .req file which is usually used to make the autosnap / restore.
  2. change ALL of the values to some value (slightly different from its current value)
  3. restore it to its current value

this will solve the sticky slider problem and do it in a systematic way. We can run it from the command line: e.g. 'unsticky.py c1psl c1ioo c1lsc'
