Hi there! This go module is currently unstable. 
Mostly, it serves as a place to aggregate 
commonly used bits and bobs for other go applications. 

A lot of this is the product of my own learning process.
As such you can expect the APIs to change without warning.

If you have any questions feel free to reach out!
