Define a wildcard multiplicity in the group adjlist to be "multiplicity x"
Define a wildcard multiplicity in the group adjlist to be "multiplicity x"

Now multiplicity is defined in exactly the same syntax as unapaired electrons,
lone pairs, and charge.  This line can be omitted altogether in the group adjlist
and still represent a wildcard.

e.g. these following adjlists for Group1 and Group2 represent identical groups:

Group1
multiplicity x
1 R u0

Group2
1 R u0
