TODO

• Resolve location of map files
• map file versioning? what happens if user changes, will next software update with a new mapping file overwrite
• long hold (for left arrow)
• ir blaster
• Integration with action event model

Events generated

IR input will cause the following events to be sent:

• EVENT_IR_DOWN - sent as soon as a new code has been sent
• EVENT_IR_REPEAT - sent out as fast as ir codes are received after IR_DOWN occurs
• EVENT_IR_PRESS - sent when no new codes are received (or a new key is pressed) prior to the IR_HOLD_TIMEOUT time
• EVENT_IR_HOLD - sent once when ir input occurs and the IR_HOLD_TIMEOUT time has been exceeded
• EVENT_IR_UP - sent when input stops (IR_KEYUP_TIME exceeded) or the ir code changes
• (under consideraton) EVENT_IR_HOLD_LONG - - sent once when ir input occurs and the IR_HOLD_LONG_TIMEOUT time has been exceeded
