// - code
/* 
	* Updated by: Sayvai Tosu (yeah... the CBSS lad) on 19/07/2008.
	* Amendment: Created a single variable named sboroughname and added IF conditional in lines 97-101 and 105.
	* Purpose of amendment: To disable list printout of SN teams based in City of London, since the MPS do not cover that single area.
	* Amendment: Created a single variable named sWard on line 138 and re-modified CASE conditionl in lines 140-164.
	* Purpose of amendment: To dynamically create new links, linking to the new SN template. NOTE: Will need to uncomment the relevant lines for either PILOT or COMPLETE rollout. Please read comments within the CASE conditional for help.
