wxdbcolinf

used with the wxdb::getcolumns functions for obtaining all retrievable information about a column's definition.

                              // foreign key table name
    wxdbcolfor  *pcolfor;     // how should this column be formatted

the destructor for this class takes care of deleting the pcolfor member if it is non-null.
