I'm using the Swiss Ephemeris software under the GPL, so I'll have to distribute their source with my source, correct?

Seriously, grab it from [here](http://www.astro.com/ftp/swisseph/?lang=e) though.

It's an amazing piece of software and I'm infinitely glad I've found it. They have two license options - one, the GPL, which only means that any code you write must also be GPL. And second, their license, which is paid. As far as I can tell, most natal chart calculators out there use this as their base library.

Long live the GPL! Their default executable, swetest, is perfect for now.

This is currently a working WordPress plugin. swetest will need to be chmod +x'd, and PHP needs access to shell_exec.

Features:
* A sortcode to display basic planetary/zodiacal positions for a given or current date.
* A JSON API (wp-admin/admin-ajax.php?action=wpephemeris&date=)

Uses UTF-8 characters for zodiac/planets.
