		sp_AllNightLog_Setup from http://FirstResponderKit.org
		
		This script sets up a database, tables, rows, and jobs for sp_AllNightLog, including:

		* Creates a database
			* Right now it''s hard-coded to use msdbCentral, that might change later
	
		* Creates tables in that database!
			* dbo.backup_configuration
				* Hold variables used by stored proc to make runtime decisions
					* RPO: Seconds, how often we look for databases that need log backups
					* Backup Path: The path we feed to Ola H''s backup proc
			* dbo.backup_worker
				* Holds list of databases and some information that helps our Agent jobs figure out if they need to take another log backup
		
		* Creates tables in msdb
			* dbo.restore_configuration
				* Holds variables used by stored proc to make runtime decisions
					* RTO: Seconds, how often to look for log backups to restore
					* Restore Path: The path we feed to sp_DatabaseRestore 
			* dbo.restore_worker
				* Holds list of databases and some information that helps our Agent jobs figure out if they need to look for files to restore
	
		 * Creates agent jobs
			* 1 job that polls sys.databases for new entries
			* 10 jobs that run to take log backups
			 * Based on a queue table
			 * Requires Ola Hallengren''s Database Backup stored proc
	
		To learn more, visit http://FirstResponderKit.org where you can download new
		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 Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000! And really, maybe not even anything less than 2016. Heh.
		 - The repository database name is hard-coded to msdbCentral.
	
		Unknown limitations of this version:
		 - None.  (If we knew them, they would be known. Duh.)
	
	     Changes - for the full list of improvements and fixes in this version, see:
	     https://github.com/BrentOzarULTD/SQL-Server-First-Responder-Kit/
	
	
		Parameter explanations:
	
		  @RunSetup	BIT, defaults to 0. When this is set to 1, it will run the setup portion to create database, tables, and worker jobs.
		  @UpdateSetup BIT, defaults to 0. When set to 1, will update existing configs for RPO/RTO and database backup/restore paths.
		  @RPOSeconds BIGINT, defaults to 30. Value in seconds you want to use to determine if a new log backup needs to be taken.
		  @BackupPath NVARCHAR(MAX), defaults to = ''D:\Backup''. You 99.99999% will need to change this path to something else. This tells Ola''s job where to put backups.
		  @Debug BIT, defaults to 0. Whent this is set to 1, it prints out dynamic SQL commands
	
	    Sample call:
		EXEC dbo.sp_AllNightLog_Setup
			@RunSetup = 1,
			@RPOSeconds = 30,
			@BackupPath = N''M:\MSSQL\Backup'',
			@Debug = 1
