/* Simple autoplace ulp based upon component position in schematic
* this ULp was origianlly written by one of the CADSOFT team I believe
* apologies for lack of full reference and acknoledgement
* run the ULP in the sch window and run place.scr in BRD
* changing the scale parameter will produce tighter/looser grouping
* Dialogue added to set sheet, scale 7 X,Y offset for the sheet of choice.  31/01/2011 by J meech.
* .ini file added to store the last settings to aid interactive placement.  31/01/2011 by J meech.
