Gives the mapping between the score and the performance time (i.e. rolled to unrolled time) according to repeat bars and jumps (to coda, da capo, etc.).
Example:
{ "ScoreID" : {
        "timemap" : [
                        {"score": {"start": "0/1", "end": "1/1"},
                         "perf":  {"start": "0/1", "end": "1/1"} },
                        {"score": {"start": "1/1", "end": "2/1"},
                          "perf": {"start": "1/1", "end": "2/1"} },
                        {"score": {"start": "2/1", "end": "3/1"},
                         "perf":  {"start": "0/1", "end": "1/1"} },
                        {"score": {"start": "3/1", "end": "4/1"},
                          "perf": {"start": "1/1", "end": "2/1"} }
                ]
        }
}
The gettimemap request corresponds to the GuidoGetTimeMap C/C++ API.
