Warn about using Fisher exact test with seeding algorithm plasma
Add template function to identify inverted measures
Respect sign of objectives
Complain about unparseable measures; fix: Fisher test is a 2x2 measure
Add DREME to the seeding algorithm enum
Copy Plasma seeding algorithm code to DREME
Translated python code from DREME for Fisher exact test
Also compute FET using the DREME code
