Detailed Description

Deal with lists of lumis in several different forms:
Compact list:
    {
    '1': [[1, 33], [35, 35], [37, 47], [49, 75], [77, 130], [133, 136]],
    '2':[[1,45],[50,80]]
    }
    where the first key is the run number, subsequent pairs are
    ranges of lumis within that run that are desired
Runs and lumis:
    {
    '1': [1,2,3,4,6,7,8,9,10],
    '2': [1,4,5,20]
    }
    where the first key is the run number and the list is a list of
    individual lumi sections. This form also takes a list of these objects
    which can be much faster than LumiList += LumiList
Run  lumi pairs:
    [[1,1], [1,2],[1,4], [2,1], [2,5], [1,10]]
    where each pair in the list is an individual run&lumi
CMSSW representation:
    '1:1-1:33,1:35,1:37-1:47,2:1-2:45,2:50-2:80'
    The string used by CMSSW in lumisToProcess or lumisToSkip
    is a subset of the compactList example above
