ImGui (Cog) setup

Most of my plugins come with debugging tools built with ImGui.

The most popular ImGui solution seems to be Cog, which I believe is the most mature solution (as of writing). That's why I have standardized all my ImGui debugging tools with this plugin.

Cog is NOT required to be installed to install any of my plugins.

My plugins use preprocessor macro's to detect if Cog is installed. If it is, then enable Cog related code. If it isn't, disable it and your IDE and compiler will ignore it.

This documentation will cover how to use it and how my code is automatically enabled or disabled depending on this plugins presence.
