 An implementation of HTML template by way of the microdata mechanism.
 ### The Gist  
 This JavaScript module should simplify adding dynamic content to HTML documents while staying true to the recommendations of web standards. There are no dependencies here except the JavaScript [ECMA5 standard](http://www.ecma-international.org/ecma-262/5.1/) which enjoys [nearly universal support](http://kangax.github.io/compat-table/es5/) in modern browsers. Also, since the HTML recommendations for integral technologies such as [template](https://www.w3.org/TR/html52/semantics-scripting.html#the-template-element) and [microdata](https://www.w3.org/TR/microdata/) are variably implemented by modern browsers, this module serves as a [polyfill](https://en.wikipedia.org/wiki/Polyfill) to assure reliable results. Best of all, this methodology encourages the writing of low-dependency JavaScript and perfectly valid HTML — even within fully-functional templated markup.
