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. 
Some formatting issues:

```java
if (page.getLon() != noLon && page.getLat() != noLat) {
```
