Common code for all of Kielson's mods.
Kielson's API is a library mod with common code for all of Kielson's mods.
It contains many functions and variables that other of Kielson's mods might need. Kielson's API helps a lot in maintainting other Kielson's mods.
When there is an update needed to a function or some variable Kielson's API makes it easier by having that piece of code in one place instead of in every project. For example this means having to update one project, instead of three. This saves time and makes process of updating much easier.
