        New Development: No             JIRA Issue: No         Ready for Test: Yes      Interface Changes: No What Interface Changed: Please list interface changes          Test Programs: List test programs   Put in Release Notes: Yes              Module(s): Module Names change impacts.            Description: Describe your changes here...

parallel_cont.py: Added the timerange parameter to imager_cont and
                  used its value (as against self.timerange) to set
                  the time range selection. 

pimager.py: Added ptime paramter to allow scattering the data along
            the time axis.  ptime=False (default setting) works as
            before.  ptime=True scatters along time axis.
