ENH: improvements for surfaceIntersection (issue #450)

- adjust for updates in 'develop'

- change surfaceIntersection constructor to take a dictionary of
  options.

        tolerance      | Edge-length tolerance          | scalar | 1e-3
        allowEdgeHits  | Edge-end cuts another edge     | bool   | true
        avoidDuplicates | Reduce the number of duplicate points    | bool | true
        warnDegenerate | Number of warnings about degenerate edges | label | 0
