Summary: Counts no longer work in classifications

Initial Comment:
The old inplementation of classification shader 
allowed the number of features in each bin to be 
displayed. e.g.

(0,100] [20]
(100,200] [21]

etc.  However, with the move to a new architecture for 
classification shaders this feature was not 
reimplemented.

The reason was that instead of one classifier for all 
types a suite of individual classifiers was introduced.

See the uk.ac.leeds.ccg.geotools.classification 
package.

It was felt that duplicating the count code in each 
one was a waste so it was to be split out into a 
classification stats class, which would be used by 
classification shader to do the counting.

To fix the bug the stats class needs finishing and 
testing and classificationShader needs changeing to 
use it.

Fixed using the ClassifierStats package.

Counts are now displayed correctly, though ClassifierStats 
could do with some optimizations as it is clearly 
inefficent.
