-# Title: Simple Image Figure tag for Jekyll
-# Author: Brandon Mathis http://brandonmathis.com
-# Description: Easily output images in <figure> with an optional <figcaption> and class names.
-#
-# Syntax {% figure [class name(s)] url [caption text] %}
-#
-# Example:
-# {% figure left half http://site.com/images/ninja.png Ninja Attack! %}
-#
-# Output:
-# <figure class='left half'><img src="http://site.com/images/ninja.png"><figcaption>Ninja Attack!</figcaption></figure>
-#
-# Example 2 (image with caption)
-# {% figure /images/ninja.png Ninja Attack! %}
-#
-# Output:
-# <figure><img src="/images/ninja.png"><figcaption>Ninja Attack!</figcaption></figure>
-#
-# Example 3 (just an image with classes)
-# {% figure right /images/ninja.png %}
-#
-# Output:
-# <figure><img class="right" src="/images/ninja.png"></figure>
