AIGL CC Stands for a ImGui CC (ImGui is Immediate Mode Gui)
Its a GUI/UI lib that allows you to make guis, but you pull the events manually and you render stuff manually.
Examples are at Examples folder
You can make your own elements more on that on the docs.
To setup this you need to have your program and the uilib folder in the same directory. You can also put the parent of uilib folder to package.path.
