@version 1.0

Note: Detect.js is a JavaScript library to detect platforms and versions based on the navigator.userAgent string. This code is based on, and modified from, the original work of Tobie Langel's UA-Parser: https://github.com/tobie/ua-parser. UA-Parser is subsequently a port of BrowserScope's user agent string parser.

As initially touted, the biggest contribution to this code is the work of Steve Souders and the list of regex tests.

• AMD/Common.js support
• Supports device, os and browser detection. Defaults to null for values family, major, minor and patch if not able to detect
• ua.toString('type'): Returns results as a string
  • defaults: to the browser object but you can specify os or device as well
• ua.toVersionString('type'): Returns a version string
  • defaults: to the browser object but you can specify os or device as well
