A hook library that can be used with BeatmaniaIIDX games that run the ezusb
FX2 IO board (e.g. 14-24). It allows you to exit the game by pressing Start P1 + 
Start P2 + VEFX + Effect simultaneously. This is very useful if you want an
option to exit back to your desktop without having a keyboard attached.

The exit hook lib must be loaded like any other hook lib you are already
injecting to the game using either *inject* or *launcher* (depending on the game
version). The order for the hook libs is important as they are loaded in the 
order specified for the inject/launcher call. The entry in the *gamestart.bat* 
file should look like this for inject:
*inject iidxhook3.dll -K iidx-ezusb2-exit-hook.dll bm2dx.exe ...*
...and for launcher:
*launcher -K iidxhook4.dll -K iidx-ezusb2-exit-hook.dll bm2dx.dll ...*

Where iidxhook3 is used for 14-15 and iidxhook4 for 20-24.
