A new type of account has been added to the Patchworks model. A MetaAccount sums other account values, and optionally multiple these values by a coefficient. An example would be to multiply harvest patch frequency accounts by a landing establishment cost.

Fix unique symbology for point themes.

Quote fields in TableQuery if required.

The query language syntax has been extended to allow subscripts on database variables. The purpose od the subscripts is to allow direct addressing of values from periods other than the default period that the table is querying. The values of the subscript can address an absolute period (e.g. [0] for period zero), or a relative period (e.g. the previous [-1] or subsequent [+1]). When a subscript references a period that is out of range then a block or zero value will be returned, as appropriate.

A new mechanism has been developed to allow complex data summaries. The new class is the CrosstabStore, and it is designed to replace the DataSlice and CrosstabReport classes. The new mechanism will summarize data into a table format. The table can then be exported to CSV or DBF, or formatted using any of the available report types.
