This plugin allows the user to quickly & easily embed a Prezi in Wordpress site by directly implementing the published 
iframe embed code.

== Description ==

This plugin, like most things useful, grew out of a need. I had a Prezi and I had a WordPress blog. I Googled for a 
few hours, trying to find a way to embed one within the other, and found some dirty hacks that ended up not working, 
as well as a plugin or two that didn't work, or only half worked. When I realized that there were no *good* solutions 
for this issue, I decided to create one.

This plugin is based on simplicity, making it extremely robust. On the back end, it is actually only a few lines of code. 
It takes the embed code that Prezi provides when click the share option and simply inserts the values that you
need before rendering a working Prezi.

I hope that you all find this plugin as useful as I have.

PS: If this plugin is helpful, please take a moment to give it the rating you believe it deserves. I truly appreciate 
your support!

== Installation ==

1. Upload `prezi-embedder` to the `/wp-content/plugins/` directory
1. Activate the plugin through the 'Plugins' menu in WordPress
1. Place `[prezi id="<Prezi ID>"]` in any post or page were you want to embed a Prezi.

To find your Prezi ID, the easiest solution is to simply copy the URL of your Prezi, which should look something 
like this: *http://prezi.com/<Prezi ID>/<Prezi Slug>*. If you paste that URL exactly as it is, the plugin is 
now smart enough to extract the ID for you. Alternatively, if you would like to do it the hard way, you can 
manually extract the <Prezi ID> from that same URL.

= Prezi Embedder Options =

In addition to a simple embed, you can also set some additional embed options:

1. width (default = 500)
1. height (default = 400)
1. lock_to_path (default = 0)

With **lock_to_path**, the default value allows viewers to pan & zoom freely. If you wish to constrain viewers 
to simple backward and forward steps, set `lock_to_path=1`.

The following shortcode is equivalent to `[prezi id="<Prezi ID>"]`, with defalut values explicitly set:

`[prezi id="<Prezi ID>" width=500 height=400 lock_to_path=0]`
