GridRow (Constructor)

This is the constructor used to construct a GridRow. The Grid Row has two variations of the constructor:

CONSTRUCTOR GridRow(owner as Grid)
CONSTRUCTOR GridRow(defaultCell as GridRow,rowHeight as Integer)

owner:
The owner is needed so the row can set its default values,
such as default cell and row height. The row will only copy
the default value references and then get rid of the reference
to the Grid. This means that once the row has been constructed
then the Row will have no knowledge of the Grid control.

defaultCell:
The value of the default cell will be used as a base when
cells in the rows become a valid writable cells.

Note: This default cell has no affect on cell substitution
at rendering time, where virtual cells are filled
with the master default cell.


rowHeight:
The height of the new row.
