Why use BlockEditAPI?

BlockEditAPI is a super easy-to-use library that saves a lot of time. It already does the NMS work for you, and it contains useful utilities that save plenty of time and reduce boilerplate code. BlockEditAPI performs really well. It can modify up to 15 million blocks per second!
