`trunc(html, limit, options?)`

Returns the result of truncating the provided html. A plain-text version is provided as well.

var html = 'the force is <strong>with this one</strong>. some more rubbish';
trunc(html, 30);
// <-
//    { html: 'the force is <strong>with this one</strong>. …',
//      text: 'the force is with this one. …' }

`limit`

Maximum amount of text characters allowed. When the limit is reached, the algorithm will trace back to the last word separator and trim the rest into a … glyph.

`options.ignoreTags`

If you'd like to supress certain HTML tags from being output you can provide an array of tags to be excluded, set ignoreTags to something like ['strong'].

`options.imageAltText`

If you'd like to use the alt attribute for the text portion of the result, instead of dropping images entirely in text flavor, set imageAltText to true.

`options.sanitizer`

Options passed to insane. Note that these options are overridden by the options provided by trunc-html, so you can't use transformText, which trunc-html reserves for itself.
