Ticket #491 (closed Defect: fixed)
Change AVISO tools to auto-detect timestep for DT datasets instead of using hard-coded 7-day timestep

In April 2007, AVISO announced they were republishing the Delayed Time (DT) datasets at a 1-day timestep instead of a 7-day timestep. They said this was being done on an experimental basis and they created special subdirectories on their FTP server for these new datasets. But sometime between then and now, they switched their OPeNDAP versions of the DT data to use the 1-day data. They did this without announcing it or creating new OPeNDAP URLs for the so-called experimental data.
This caused a problem for MGET's AVISO tools. Currently, these tools assume that all DT datasets use a 7-day timestep. This knowledge is hard-coded into the tools to make them slightly more efficient. (This seemed like a safe choice, as the DT datasets have been 7-day products for their entire lifetime of over 10 years.)
As a consequence, the tools are completely broken. They stretch 1 year's worth of 1-day data over 7 years. None of the dates match up with reality. This is obviously a major problem that must be fixed ASAP.
