ABBR
====

Abbr is a JavaScript library / function for finding, highlighting and annotating abbreviations in text.

It goes through text and wrapps acronyms (or anything you want) in `<abbr>` tags (or other of choice), and gives them
`title` attribute with explanation (again, customizable).

It needs **no extra markup**, all is done automatically. Just tell it what words you want to explain, and it'll do it.

Usage
-----

Abbr takes the following (default) arguments:

```js
{
	// selector in which to search for abbreviations
	where: 'body',
	// abbreviation list - word: explanation
	words: {},
	// Tag used to mark the matches
	tag: 'abbr',
	// Attribute holding the "description" to be added to the tag
	attr: 'title',
	// Case insensitive
	ci: true,
	// tags that shall not be traversed (in addition to opts.tag)
	excluded: ['script', 'style', 'code', 'head', 'textarea', 'embed'],
	// Extra excluded (doesn't overwrite the original list)
	exclude: []
}
```

All config options are optional (though, obviously, you don't want to leave `words` empty).

To run it, simply call (example):

```js
abbr({
	where: 'article',
	words: {
		'NSA': 'National Spying Agency',
		'Putin': 'Bear rider'
	}
});
```
