+# 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>
+#
