Observations/Coordinates - Number Column Right Click Menu

Some of the options on this right click menu are duplicated with the Code column.  Listed below however are those items unique to the Number column.

• Renumber: Allows the selected observations to be renumbered starting at a given number, at a given interval, with prefix and suffixes if required.
• Add Prefix: Adds a given prefix the the selected points.
• Add Suffix: Adds a given suffix to the selected points.
• Number to -99: Renumbers the selected points to -99.  This flags the observation as a control shot with a slope distance.
• Number to -88: Renumbers the selected points to -88.  Only has an effect if the reading is first in the list.  Of so, then the -88 indicates that the rest of the observations Hz Angles should be interpreted as whole circle bearings.
• Number to Code: Similar to Swap Code and Number from the Code column. But this option changes the Number to -99 in the process so that it is converted into a control observation in one operation.
