/**
 * Represents a forward-only iterator over a result set, which will lazily iterate
 * the results. The underlying ResultSet can be closed by calling the
 * {@link org.skife.jdbi.v2.ResultIterator#close()} method.
 * 
 * The default implementation of ResultIterator will automatically close
 * the result set after the last element has been retrieved via next() and
 * hasNext() is called (which will return false). This allows for iteration
 * over the results with automagic resource cleanup.
 * 
 * The remove() operation is not supported in the default
 * version, and will raise an UnsupportedOperationException
