* new convenience method addUniqueValueRules in OL.!StyleMap. This can actually be used to achieve what I was trying to show in the example of this ticket's description. * some refactoring of OL.Style to remove duplicate code (with tests) * a new example showing how to add a "unique value" legend to a point layer using the new addUniqueValueRules method * Rule.symbolizer can now also be just a symbolizer, instead of a hash of symbolizers keyed by "Point", "Line", "Polygon". This will make things even simpler (as can be seen in the styles-unique.html example) r=tschaub (closes #1373) git-svn-id: http://svn.openlayers.org/trunk/openlayers@6396 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
