/**
* Handles writing of a StarTable in a column-oriented
* FITS binary table format.
* The table data is stored in a BINTABLE extension which has a single row;
* each cell in this row contains the data for an entire column of the
* represented table.
*
* This rather specialised format may provide good performance for
* certain operations on very large, especially very wide, tables.
* Although it is FITS and can therefore be used in principle for data
* interchange, in practice most non-STIL processors are unlikely to
* be able to do much useful with it.
