AngularJS Directive for horizontal scrolling

Horizontal scrolling on the web always seems better on paper than in practice. This is my attempt at a sane, user-friendly approach to that problem. Slidebox is friendly to both desktop computers and touch devices.

This will overlay two large buttons on either side of the content for scrolling left and right. Hover the mouse over a button to scroll in that direction; the closer to the edge the mouse goes, the faster the content scrolls. And the regular old scrollbar is still there for use. On a touch device, the content scrolls at a constant speed while one of the control buttons is pressed.

All you need is js/slidebox.js, css/slidebox.css, and the images. Add those to your project and include the 'Slidebox' module. Everything else in this repository has to do with the demo and unit tests.

To view the demo, clone the repository into a local directory and open demo.html.

    Your content here!
</slidebox>```

All attributes are optional.

**speed** -- Default value is 25.

**content-width** -- Width of the *inner* content.  May be specified in 
px, em, or any other standard CSS unit Alternately, you may specify the
width in your stylesheet by selecting either the "slidebox-content" class
or another class specified with the "content-class" attribute.

**content-class** -- Space-seperated class names to be applied to the
*inner* content div.
