dap4 fixes
Made a new string tokenizer generalized for single and multicharacter separators in StringUtil2.java.  Refactored (or started to refactor) NcMLReader.java to use the new tokenizer.  Made a new test class for StringUtil2 and wrote unit tests for getTokens
Refactoring to use new getTokens method in StringUtils2
Refactored annoying if-else chain into a switch statement, handled the case of empty separator, more unit tests.
Fixed problem of zero rank array initialization. Iterator now uses factory method for new index.  Index0D now has an override of the set(int[]) method.  Created unit test for rank zero array initializaion.
added documentation to NcML cookbook for removing variable attributes and global attributes
minor stuff
fix unit test
add logicalReduce to NcML
fix unit tests
In ToolsUI->FeatureTypes->PointFeature, the number of observations that a feature has is counted when the user clicks on its row in the tables. However, the new count wasn't being reflected in the UI until the user clicks some OTHER feature. That's been fixed.
Moved some tests that were referring to resources on testdata out of cdm and into cdm-test.
fix radar controller to disable if radar subdirectory is not present;
add unit test for ncml logicalReduce
added a bunch of .trim() to .getText() to eliminate trailing white space that caused problems with aan hdf header
In ToolsUI->FeatureTypes->PointFeatures:
    * Stale profile data is cleared when a new dataset is selected.
    * The STATION_PROFILE split pane now defaults to an even split between the station table above and the profile table below.
    * The station table should now update any time a new feature collection is selected. Before, you'd need to mouse-over the map in order to force a repaint.
