Empty molecular graph #48

Closed rapodaca closed 2 years ago

rapodaca commented 2 years ago

Grammar supports the empty string, so the molecular graph can be empty. At least one statement is inconsistent:

"A Dialect molecule consists of a graph with at least one node and zero or more edges."

All such occurrences should be corrected to allow empty graphs.
