Update Inventory using Lancer PN Input file

	For 2007

	The expected input text file format is each line as:
	LancerPN   p5Price   UnitCost	   p6price		p1price		p2price  
	(fields above are delimited (separated) by tabs)

	The input program will automaticly prefix each input PN with "LA"
	before looking it up.

	The UnitCost will replace the Greux Last and Average Cost
