MergeNodes: Merge given node set of an APFA
In gRapfa: Acyclic Probabilistic Finite Automata

Merges two nodes (at the same level) in an APFA, returning the resulting APFA.

1	MergeNodes(G, nodeset, NS = NULL, setLayout = TRUE)

`G`	`G` is an APFA object.
`nodeset`	`nodeset` is a vector of vertex names or nodes of length two, which are to be merged.
`NS`	`NS` is the node by symbol array for G. Supplying this will speed the computations.
`setLayout`	If `setLayout=TRUE` sets XY coordinates for the graph

If necessary, more details than the description above.

Returns the APFA igraph object after merging.
