SimulateCharacteristic. Note this doesn't follow the above names with 'BLEGatt'
in them. I think the 'BLEGatt' is redundant, you may want to refactor that out
in a later patch.

[gogerald1, 2016/02/24 16:09:06]

Follow above names "BLEGatt" for now since all the other data structures and
interfaces followed. Refactor them out in a separate path at the end.
