/* %start-doc actions RenumberBlock

The @code{RenumberBlocks()} action renumbers all selected refdesses on
the pcb.

Usage: RenumberBlock(oldnum,newnum)

All selected elements are renumbered by adding (newnum-oldnum) to
the existing number.

To invoke it, use the command window, usually by typing ":".

Example:

@code{RenumberBlock(100,200)} will change R213 to R313.
