AppMain.cpp - this is where the fun begins!

There is a lot that happens under the hood with wxWidgets. We don't need to worry about that. All we need to worry about is this this line of code here: <source lang="cpp">IMPLEMENT_APP(Pcsx2App)</source> which can be found in AppMain.cpp. This macro tells the wxWidgets framework that Pcsx2App is the wxWidgets app that we want to fire up.
