  Database Base Data Getter
  =========================================================================================================================================
  Simon Strutt        Jan 2011
  =========================================================================================================================================

 Version 1 
  - Initial creation

 Version 1.1 - Mar 2011
 - Bugfix: Where VC provides no VM FolderID, VM is assigned incorrect VC folder path - now catch as error
 - Bugfix: VM's having no IPAddress in vCentre not handled properly, causing errors - now handled silently
 - Bugfix: Added vmvcid to better handle Lab Manager v4 VM's with duplicate UUIDs
 - Bugfix: ESX's moving clusters causes duplicate ESX entries - old ESX/cluster entry now gets expired
 - Added snapshot info

 Version 1.2 - Mar 2011
 - Bugfix: Snapshot sizes not right (known PowerCLI bug in Get-Snapshot that I'd wrongly assumed to be fixed)
 - Added population of snap.vrange (is snapshot a vRanger snapshot)
 - Added ESX extended data (inc IP - needs further work), ntp, hba and nic info
 - Consolidated SQL query strings

Version 1.2.1 - Mar 2011
 - Bugfix: Standalone ESX's cause SQL INSERT error (as clid isn't defined)
 - Bugfix: Script crash when unable to get ESX NIC/HBA info (happens when ESX not connected)
 - Bugfix: ESX name wrong when known by VC with IP Address (name now extracted with regex to handle name being IP)
 
Version 1.2.2 - Apr 2011
 - Workaround: DV switch doesn't have VLAN ID in same place as Port Group causing SQL INSERT fail, caught and set to NULL
 
Version 2.0 - Jun 2011
 - Changed to Async/PS Jobs in order to run against multiple vCentre's simultaneously
  - vCentre data mining moved to sub-script
  - Moved MySQL functions out to library file (shared between main and sub-script)
  - Enforce run in 32 bit environment (PowerCLI bug workaround, vSphere scripts crash Powershell when launched as background jobs in 64bit)
 - Added basic support for vApp VM's (name add to vm_ext, vm folder now supported)
 - Added logging of errors to database
 - Added sanity checks (make sure total no of clusters, ESXs, VMs in db matches VC)
 - Added basic support for distributed switches, and added special network types (mgmt, vmk, ft)
 - Improved deleted VM handling
 - Change logging timestamp from xxx secs to hh:mm:ss.msec
 - Bugfix: Old VMDK's / vNIC's don't get removed from VM's - additional now deleted NOT WORKING YET, NIC's get added and deleted on some VM's  **** TO FIX ****
 
Version 2.1 - Sep 2011
 - Added check for sub-script fail
 
Version 2.2 - Nov 2011
 - Allow db override via command line param

 Future improvements
 - Add daily capacity report
 - Bugfix: ESX's moving clusters should be handled by main INSERT UPDATE, remove/rework ESX duplicate bugfix - maybe catch as major error?
 - Add HA settings (isolation response, admin control, etc)
 - Add VM CBT
 - Add VM custom attributes
 - Add VM resource limits / shares
 - Calculate total VM disk usage - not sure really required
 - Add state change datetime stamp
 - Catch all Powershell execptions in order to increment counter (add errors to db at later date)
 - Add who did what (event log extracting)
