+ *
+ * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
+ *
+ * Solution:
+ *
+ * We assume the radius of the polygon is half the size of the canvas at first
+ * at each index we check if the text overlaps.
+ *
+ * Where it does, we store that angle and that index.
+ *
+ * After finding the largest index and angle we calculate how much we need to remove
+ * from the shape radius to move the point inwards by that x.
+ *
+ * We average the left and right distances to get the maximum shape radius that can fit in the box
+ * along with labels.
+ *
+ * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
+ * on each side, removing that from the size, halving it and adding the left x protrusion width.
+ *
+ * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
+ * and position it in the most space efficient manner

+/*!
+ * @copyright Copyright © Kartik Visweswaran, Krajee.com, 2014 - 2015
+ * @version 4.1.8
+ *
+ * File input styled for Bootstrap 3.0 that utilizes HTML5 File Input's advanced
+ * features including the FileReader API.
+ *
+ * The plugin drastically enhances the HTML file input to preview multiple files on the client before
+ * upload. In addition it provides the ability to preview content of images, text, videos, audio, html,
+ * flash and other objects. It also offers the ability to upload and delete files using AJAX, and add
+ * files in batches (i.e. preview, append, or remove before upload).
+ *
+ * Author: Kartik Visweswaran
