getNextFreeMultiIndexForSource
	  
      
      This returns the next multi index that's available
for the given source plug. This is the same
as getNextFreeMultiIndex, but we assume the
attr is a source plug, not destination. This command is useful when
connecting nodes where one wishes to connect to the first available multi
on a node, i.e. the first element that is not already connected.
