Applying EVLA on-line flags

Currently, the EVLA does not apply ion-line flags. This includes time when the telescope was not on source and the time needed for the subreflector to come to its final position.

Two tools can be used to apply these flags after the observation:

1) using the script flagants.py on the asdm raw data file

2) importing data with the newly developed importevla task

Note that the importevla task is not available in the official release (yet) and has not been extensively tested. Thus we like to concentrate on how to use the flagants.py script:

The following steps are needed.
