Grant Ingersoll updated SOLR-1131:
----------------------------------

    Attachment: SOLR-1131.patch

Updated to include some of Yonik's concerns about implementation.  I didn't get 
his Javadoc changes b/c they were too hard to determine the differences.

Other notes:
# Removed PlusMinusField and just used the PointType for those tests.  This 
then allowed me to move the registerPoly static method to the 
CoordinateFieldType
# I kept the n-dimensional point.  All of our distances work on vectors, I see 
no reason not to keep them.  Performance wise, most people w/ dimension of 2 or 
3 will see little if any difference between this and specifically calling out a 
lat/lon field type.
# I believe I cleaned up the public method stuff so that helper methods are now 
package private.

> Allow a single field type to index multiple fields

> In a few special cases, it makes sense for a single "field" (the concept) to 
> be indexed as a set of Fields (lucene Field).  Consider SOLR-773.  The 
> concept "point" may be best indexed in a variety of ways:
>  * geohash (sincle lucene field)
>  * lat field, lon field (two double fields)
>  * cartesian tiers (a series of fields with tokens to say if it exists within 
> that region)
