[Suggestion] Proper documentation for developers

[Benjamin-Mueggenburg]

Being that this tool is meant to be used as a tool for developers, there should also be more documentation on available functions and methods that they have available to use, and how to use them.

Currently it only has a few examples, but doesn't quite show what is available to use. Further explaining how openIoE works will allow for developers to better integrate it into existing projects - as well as allow for people to understand the inner workings for education purposes or open source contribution
