/**
 *  WAccount Servlet.
 *  <p>
 *  The servlet is invoked by a parent window via
 *  <code>
 *  WAccount?FormName=formName%ColumnName=columnName
 *  </code>
 *  and assumes that in the opening window/form there are two fields
 *  <code>
 *  opener.document.formName.columnName - The (hidden) field for the ID
 *  opener.document.formName.columnName_D - The display field for the value
 *  </code>
 *  When selecting an entry, the window is closed and the value of the two fields set.
