Renamed few directories and removed stray console messages
Snapshots will not be saved if already present
Only List no option added

This option lets user see the names of the companies but does not actually send any reminder to company.
This is different from demo where an actual mail is sent to the test mail id.
Added functionality to remove a shipment from being tracked.

It will not be tracked again unless it falls under automatic vigilance.
    Most recent shipment is shown first
