A lightweight and versatile spin box component for ember.js applications.

Although the development of this component was intended more as a learning experience for myself, ember-spin-box received some very positive initial feedback from the community, and was even featured in the e-mail newsletter, Ember Weekly (issue #60). It was one of my first stabs at creating a truly reusable component that could easily be used in many different applications, and could be built upon to create more complex interfaces. In fact, ember-date-picker is another component I created, which uses ember-spin-box as its core means of user interaction.
