Documentation update

[neogeek]

I've made two minor changes to each of the lib/ files:

• module.exports has been to the bottom of the file. This changes how the function is displayed in the documentation. Right now each function shows up as module.exports(attribute). After this change they will show up as functionName(attribute).
• Extraneous whitespace has been removed around the examples. Currently the examples are displayed with a leading new line and extra indentation.

I've also added an optional badge to the README linking off to live documentation of this codebase. This page also has links to documentation for all other published releases of this package.
