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

    Variables you can use:

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

        @StartDate: The date you want to start searching on, defaults to last 7 days

        @EndDate: The date you want to stop searching on, defaults to current date

        @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

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

        @TargetSessionType: Can be ''ring_buffer'' or ''event_file''. Leave NULL to auto-detect.

        @OutputDatabaseName: If you want to output information to a specific database

        @OutputSchemaName: Specify a schema name to output information to a specific Schema

        @OutputTableName: Specify table name to to output information to a specific table

    versions for free, watch training videos on how it works, get more info on
    the findings, contribute your own code, and more.

    Known limitations of this version:
     - Only SQL Server 2012 and newer is supported
     - 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.

    Unknown limitations of this version:
     - None.  (If we knew them, they would be known. Duh.)
