Array index out of bounds exception caused by some problems with i18n substitution of strings. A couple of key names were incorrect in the english properties and it seems the the resource bundle trims white space from the start of a value. Fixed.

getStructure() now returns an empty set of instances where all attributes are String attributes. This now allows the CSVLoader to be used in a cross-validation run in the KnowledgeFlow. This was not possible previously because the ClassValuePicker prevents configuration if the class is numeric. Improvements to the ClassValuePicker's customizer now allow a label to be specified when the upstream data source can't provide full structure information on nominal attributes.

Changed paths:
   M /branches/stable-3-6/weka/src/main/java/weka/core/converters/DatabaseLoader.java

getStructure() and getDataSet() were painfully slow when determining the structure of largish data sets with many nominal attributes. For batch retrieval getStructure() now returns an approximate structure (where potentially nominal attributes are set to String). getDataSet() now uses InstanceQuery (which determines the true structure on the fly as the data is loaded from the database). Incremental retrieval is still problematic in the case where there are many nominal attributes as the true structure has to be determined before the instances are streamed.

Changing database configuration now resets the Loader. Now now longer gets the loader to push the structure downstream after configuration since ClassAssigner and ClassValuePicker will pull this using the new StructureProducer interface.

Now has an option to allow the user to specify that the filter should be applied to instances that arrive after the first batch has been processed. By default these instances are returned without passing through the parser - this means that, when used with the FilteredClassifier, a test instance is always made available by this filter. If the option to enable filtering of test instances is turned on, then the filter can be used with subsequent batches, but might "consume" a test instance when used with the FilteredClassifier.

Now makes a copy of the data before sorting when creating a rule on a numeric attribute. This ensures that ties in attribute values are handled consistently and are'nt affected by sorting performed for any previous numeric attributes. For example, before this change the best rule for iris was petallength, however, if all attributes but petalwidth are first removed then the rule on petalwidth is actually more accurate by one instance (i.e. only sorting once results, by more fortuitous ordering of ties, in better split points in terms of accuracy on the training data).
