/**
 * A class that keeps track of a row's values. A <code>Row</code> object
 * maintains an array of current column values and an array of original
 * column values, and it provides methods for getting and setting the
 * value of a column.  It also keeps track of which columns have
 * changed and whether the change was a delete, insert, or update.
 * <P>
 * Note that column numbers for rowsets start at <code>1</code>,
 * whereas the first element of an array or bitset is <code>0</code>.
 * The argument for the method <code>getColumnUpdated</code> refers to
 * the column number in the rowset (the first column is <code>1</code>);
 * the argument for <code>setColumnUpdated</code> refers to the index
 * into the rowset's internal bitset (the first bit is <code>0</code>).
