Update Docs or Create New Examples for Release

[asampat3090]

PyPi and Semver documentation

• change README.md to match website
• add CHANGELOG or HISTORY document for public releases
• set versioning conventions and document and add to Developer Notes / Tools
• instructions for a release in the Developer Notes / Tools section

Add in logger to the Readme Docs to explain how to track config and stats during runs

• example usage,

from datmo.logger import Logger

datmo_logger = Logger()
config = {'a': 1}
datmo_logger.log_config(config)
# Perform analysis to get results

result = {'a': 1}
datmo_logger.log_result(result)

• add a code / CLI example for run and rerun in repo + link them and explain in Readme docs
• create hello world example with code snippet and link to Readme Docs
