Look to move functionality of teddy.compile towards similar to other template engines

[lannonbr]

For a large amount of template engines, the compile method takes in a template and outputs a function which when given data, will render out HTML.

Here are some various other templating engines which do this:

• Pug: https://pugjs.org/api/reference.html#pugcompilesource-options
• Handlebars: http://handlebarsjs.com/ (scroll down to where it says "Compile a template in JavaScript by using Handlebars.compile")
• EJS: http://ejs.co/#docs

teddy.compile was removed in 0.6.0 but this issue is still valid because a new teddy.compile could be added later which introduces this functionality.
