Fixed instructions for using Foundation with an existing project
Adding Jasmine test framework and basic test example
The top bar has been modified to calculate height based on sticky / fixed
positioning element.  Additionally, rather than jiggering the height around
manually, the ability to add custom CSS rules for a Foundation component
has been added to the base Foundation.js (addCustomRule).  It also supports
the built-in media query names (small, medium, and large) generated by the
SASS compilation.

I also updated the docs to clarify the need for contain-to-grid and fixed
to be on the same element.

Dropdown hover example
avoid treating zero as a falsey value

This allows you to use : 

```
$(document).foundation('magellan', { threshold: 0 })
```
and not have it be overridden with some unrelated number.
