Improve library summary and quick start section #59
Description
Is your change request related to a problem? Please describe.
As described in the documentation section of the Library Guidelines, Contributors libraries are expected to have in their README a short summary of the library's purpose, installation instructions, a quick start with a minimal usage example, and links to the documentation and contributing guide.
The library has a summary and quick start in the README, but they read almost like minimal reference documentation and deserve some love.
Describe the solution you'd like
The library summary should, in a couple sentences, motivate why this library exists. Right now the description just states it's an alternative to moment.js, but we should really add a couple sentences about what this library allows you to do (beyond a reference to a JS library).
The quick start really ought to demonstrate how to create and use some common formatters, like a number and a date, both via parsing string formats or via constructors (as described in #22).
The current quick start could be the start of more fleshed out documentation in the docs directory.
