// GetValues("Accept") would return an array of two strings: "text/plain"
// and "text/html".
// Arguments:
// header - Name of the header.
// Return Value:
// string[] - array of parsed string objects
/// <devdoc>
/// <para>
/// Gets an array of header values stored in a
/// header.
/// </para>
/// </devdoc>
