Possible that a record may have only one or more of:
 - a start date/time
 - a stop date/time
 - a scheduled tech
 - a Est.Qty (i.e. 2 hours)
So still need to SHOW on the schedule so rest can be done (i.e. be able to assign, be able to estimate, be able to set start AND stop date/time)

Graphical Schedule to have three main sections:
- Date Navigator:
- Schedule: 
--if have wo with Est Qty, tech assigned and start date/time (stop is derived fro Est Qty or is manually entered)
--if have wo with Est Qty, no tech assigned, and start date/time (stop is derived fro Est Qty or is manually entered)
--(unassigned column if separate view. if merged, the unassigned still MUST be shown on this Schedule)
--(by default Schedule only shows non-Closed. Menu option to see Closed wo's scheduled items)

- Not Scheduled area: 
--could have non-Closed wo with nothing scheduled
--could have non-Closed wo with Est Qty only (no start and no tech assigned)
--could have non-Closed wo with Est Qty, tech assigned, but not a start date/time
--could have non-Closed wo with tech assigned, but no Est Qty nor start date/time

Only shows on the graphical Schedule screen if:
 - HAS BOTH a start date/time AND a stop date/time
2. WOscheduled record  with Start date/time and Stop date/time, with Est. Qty, assigned to specific resource (all options are identified) (shows for the specific tech)


Listed in Unassigned area of graphical Schedule screen if:
 - a tech is NOT specifically assigned
 - HAS a start date/time AND a stop date/time
3. WOscheduled record  with Start date/time and Stop date/time, with Est. Qty, but tech not assigned
5. WOscheduled record with Start date/time, with Est. Qty (stop date/time is derived from the Est. Qty), not assigned
