Not sure what I'm looking for

[LanceDH]

Hi,

So I have an addon for quite some time now but it's getting a bit big and messy since it's all in 1 file.
Now I want to split it up in different files (think classes in say C++) but I have absolutely no idea how to do it.
I've tried searching for guides about it but I don't quite know what exactly I'm looking for, so I haven't found anything.
To give an idea about the addon:
It tracks different things related to battlegrounds (mainly randoms) such as your honor/conquest points, your kills/deaths in the current bg, your exp gained, ....
Each one of those tracks is like its own class so to speak and i want to create a seperate file for them, rather than have all of them in 1 big spaghetti code.
The main thing I'm looking for is something where I can just write a file and link it to the core myself.
