	This script checks for and analyzes deadlocks from the system health session or a custom extended event path

	Variables you can use:
		@Top: Use if you want to limit the number of deadlocks to return.
			  This is ordered by event date ascending

		@DatabaseName: If you want to filter to a specific database

		@StartDate: The date you want to start searching on.

		@EndDate: The date you want to stop searching on.

		@ObjectName: If you want to filter to a specific able. 
					 The object name has to be fully qualified ''Database.Schema.Table''

		@StoredProcName: If you want to search for a single stored proc
					 The proc name has to be fully qualified ''Database.Schema.Sproc''
		
		@AppName: If you want to filter to a specific application
		
		@HostName: If you want to filter to a specific host
		
		@LoginName: If you want to filter to a specific login

		@EventSessionPath: If you want to point this at an XE session rather than the system health session.

	Known limitations of this version:
	 - Only 2012+ is supported (2008 and 2008R2 are kaput in 2019, so I''m not putting time into them)
	 - If your tables have weird characters in them (https://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references) you may get errors trying to parse the XML.
	   I took a long look at this one, and:
		1) Trying to account for all the weird places these could crop up is a losing effort. 
		2) Replace is slow af on lots of XML.
	- Your mom.
