Object used to maintain state.

# State pattern

**The state pattern tries to deal with common state issues by making it immutable and utilizing copy-on-write.**

This pattern kind of emerged for me out of necessity while working with databases. I had inherited quite a bit of code that was analyzing, creating, editing, and removing data, all in a couple of quite large, borderline godlike, functions.

I can't get into too much detail, but more often than not, the same bit of data was fetched over and over, making it slow. Sometimes bits of the code was working on data that had already been edited by other bits of the code, and whenever there was an error, it tended to leave the data in a very iffy state.

I did not like this one bit.
