Code review comment for lp:~epics-core/epics-gateway/dbe_props

Thanks. The python prerequisites are thus argparse (RHEL6's RPM python-argparse) and tappy (PyPI package tap.py).

The tests all fail for me, but they do now run:

tux% cat runTests.py.tap
# TAP results for DBEValueTest
not ok 1 - DBE_VALUE monitor on an ai - value changes generate events.
# TAP results for DBELogTest
not ok 2 - DBE_LOG monitor on an ai with an ADEL - leaving the deadband generates events.
# TAP results for DBEAlarmTest
not ok 3 - DBE_ALARM monitor on an ai with two alarm levels - crossing the level generates updates
# TAP results for DBEPropTest
not ok 4 - DBE_PROPERTY monitor on an ai - value changes generate no events; property changes generate events.
# TAP results for PropertyCacheTest
not ok 5 - Get PV (value) through GW - change HIGH directly - get the DBR_CTRL of the PV through GW
not ok 6 - Get PV (value) through GW - disconnect client - change HIGH directly - get the DBR_CTRL of the PV through GW
not ok 7 - Monitor PV (value events) through GW - change HIGH directly - get the DBR_CTRL of the PV through GW
