Geographic intersect utilities using WGS84 datum

Installation
-------------
    $ npm install wgs84-intersect-util

Methods
--------
    intersectPolygons(searchWithin, polygons)
> Intersect a list of GeoJSON polygons with a given GeoJSON polygon
>
> **searchWithin**:  *object*,  GeoJSON polygon
>
> **polygons**:  *array*,  GeoJSON polygons
>
> **Returns**
>
> *array*, a list of polygons that intersect `searchWithin`

    intersectLineBBox(line, bbox)
> Intersect a GeoJSON line with a bounding box
>
> **line**:  *object*, GeoJSON LineString
>
> **bbox**:  *array*, an array of bounding box coordinates in the form: [xLow, yLow, xHigh, yHigh]
>
> **Returns**
>
> *array*,  a list of GeoJSON points that represent intersection points on `bbox`

    intersectLines(searchWithin, lines)
> Intersect a list of GeoJSON LineStrings with a given GeoJSON polygon
>
> **searchWithin**:  *object*,  GeoJSON polygon
>
> **lines**:  *array*,  GeoJSON LineStrings
>
> **Returns**
>
> *array*,  a list of LineStrings that intersect `searchWithin`
