* commented out the hard coded granule beginning/ending datetime

* added RiverAvg sample iso.xml file for unit testing

* ummtest using schema version 1.6.5

* CHANGELOG

* support BasinID

* process nc.iso.xml based on collection config : "isoXmlSpatial": ["footprint"], // can be "footprint", "bbox", or "orbit"

* CHANGELOG

* move PODAAC-5770 to the Fixed section of CHANGELOG

* iso.xml use the POLYGON path, not the LINE

* code modification based on comments

* fixed compiling error

* divided over IDL

* New utility to perform XPath extraction with better logging

* better handle XPath extraction logging and remove MENDSIsoXMLSpatialTypeConstant
