Added the ability to parse coordinates from wikitext when present. It reads the values for the main coordinates of a page into an array. Depending on the number of values present it determines how to convert to decimal degrees. This is intended to work well with the geopoint type for elasticsearch allowing for distance and bounding box queries. 
Please don't touch other parts of the code. It's better for merging other changes then and only focus on your actual code.
