Add nested row/column number option to support trials with non-uniform shapes and physical gaps

[bellerbrock]

Expected Behavior

Requested by Bert at CIP. Many sweetpotato trials they deal with are planted in a way that trial-wide row and column numbers do not make sense. Fields can be shaped in a way that blocks have to be offset from one another, or placed on opposite sides of a road.

To deal with this he suggest the option to nest row/column numbers within block/rep, either by adding new design columns like 'row_in_rep; and 'col_in_rep', or by a single 'nested_coordinates' trial property that can be set to true or false. If true then allow row and col pairs to repeat within the trial, just not within the block/rep.

Need to figure out how the fieldviewer and geofieldviewer interact with this design data
