Message:

Added multiplicity guesser for Psi3Parser's UHF.

• TESTFIX: changed multp in testuhf.psi and testtwocon.psi of regression tests Parser/Psi3 due to multiplicity guesser.
• TESTFIX: changed multp in the same way in ParserPsi3UnitTest.

File:

• src/Parser/Psi3Parser.cpp (modified) (3 diffs)
