CellDataType
------------------------------------------------------------------------
Assign cell types (and editors) on a per-cell basis.

Starting with version 2.1 of the FlexGrid, several properties that
used to belong to Column objects now belong to the CellStyle. These
include DataType, Format, ComboList, DataMap, and more.

The main advantage of the new approach is that now you can associate
these elements with arbitrary cell ranges, rather than with columns
only.

This sample creates styles for entering and displaying different
data types, and assigns these styles to specific cell ranges, so
you can have dates, strings, and currencies in the same column.
