progressive examples in README.md

[alan-cugler]

Issue

Requesting a few examples to be in the README.md to give quick start examples of how to use.

Example

import deep_collection
l = ['1', 2, 3, 'sdf', True]
g = [0, 1, 2, 3]
d = [{'keys':'values'}]

#insert awesome example of deep_collection

Reasoning

Examples enable people who are browsing for a solution to gauge difficulty of adoption and give it a try.

Case Study

Me! I won't usually try a tool unless they give examples on how to use it at the get go.
