SigmaConf - A Simple Configuration Library for Science

The goal of this library is to provide config dict-like objects with the following features:

• Easy nested access, e.g. cfg['a.b.c'] instead of cfg['a']['b']['c']
• Immutability. Implemented as functional datastructures, which prevents unwanted side effects
• Composability - Configs can be easily combined, smartly merging nested structures
