correct bad min_delay setting in nest backend
correct get("list") for nest: it now return a list of tuples
TestAllToAllConnector in test_connectors_serial -- OK in hardware
properly include an exclude_modules list in glob_import. Cleaner that just commenting the import line.
Corrects bug connector refusing to connect index 0 to index 0 if it was the unique connection for postsynaptic cell 0
_standard_connect works without error if mask is all false
all connectors tests pass!!!
