/**
* This is an example application for the GraphmlParser utility for converting a graphml file
* to tab-delimited format.
* 
* Command line arguments are as follows:
* 
* -in -- Path and filename of graphML input file [required].
* 
* -out -- Path and filename of tab-delimited output file [required].
* 
* -longIDs -- [boolean, optional] If == true, then nodes will be assigned a unique Long number ID,
* 			regardless of the node ID format in the original graphML file.  Note, this ID convention is
* 			needed for data processing with Spark's GraphX library.  Default == false.    
* 
* -nAttr -- Node attributes to parse (attribute ID tags separated by commas) [optional].
* 			Default is to parse ALL node attributes.
* 
* -eAttr -- Edge attributes to parse (attribute ID tags separated by commas) [optional].
* 			Default is to parse ALL edge attributes.  
* 
* -nCoordAttr -- Node attributes to use for node co-ordinates (separated by commas) [optional].
* 				Default is NO co-ordinate data will be associated with a given node.
*   
* -nCoordConvert --  Node co-ordinate conversion [optional; may be used with 'nCoordAttr' property above]
*					Choices are: zorder2xy (z-order to x-y), zorder2xyz (z-order to x,y,z -- note: z-axis data will be discarded!)
*	    			Default is no conversion
