Implement proposal in #212

Implement proposal in #212 (closed): add error if GraphView::replace() is used with two sets for the following conditions:

Inputs conditions:

old \ new	1 node, 1 input	>1 node, 1 input	1 node, >1 inputs	>1 node, >1 inputs
1 node, 1 input	trivial	trivial	broadcast	broadcast
>1 node, 1 input	trivial	trivial	broadcast	broadcast
1 node, >1 inputs	(take first)	(take first)	same order	X
>1 node, >1 inputs	X	X	X	X

Outputs conditions:

old \ new	1 node, 1 output	>1 node, 1 output	1 node, >1 outputs	>1 node, >1 outputs
1 node, 1 output	trivial	trivial	take first	X
>1 node, 1 output	trivial	trivial	take first	X
1 node, >1 outputs	(take first)	(take first)	same order	X
>1 node, >1 outputs	X	X	X	X

Only the X cases cannot possibly be resolved deterministically with sets of node. These cases are therefore forbidden for the set-based replace() interface. The remaining cases are handled by the GraphView-based replace() interface. If they are not supported, the function returns false.
