      While using Span queries I think I've found a little bug.

      With a document like this (from the TestNearSpansOrdered unit test) :

      "w1 w2 w3 w4 w5"

      If I try to search for this span query :

      spanNear([spanNear([field:w3, field:w5], 1, true), field:w4], 0, true)

      the above document is returned and I think it should not because 'w4' is not after 'w5'.
      The 2 spans are not ordered, because there is an overlap.

      I will add a test patch in the TestNearSpansOrdered unit test.
      I will add a patch to solve this issue too.
      Basicaly it modifies the two docSpansOrdered functions to make sure that the spans does not overlap.
