 * Two nonoverlapping stretches of three residues each, i - 1, i, i + 1 and j - 1, j, j + 1,

 * if there are two H bonds characteristic of P-structure; in particular,
 *
 * Parallel Bridge(i, j) =:
 *      [Hbond(i - 1, j) and Hbond(j, i + 1)] or

 *
 * Antiparallel Bridge(i, j) =:
 *      [Hbond(i, j) and Hbond(j, i)] or
 *      [Hbond(i - 1, j + 1) and Hbond(j - 1, i + l)]
