message: Document change in test spec files.
diff: This directory contains data files for verifying
  axom::quest::findTriMeshIntersections() and related functions. Each test is
  specified by a file with the extension ".test". These text files have
  -four lines:
  +five lines:
  1. The test name, a distinctive string.
  2. The STL mesh file, relative to this directory. Suggested locations are in
  this directory or its parent.
  -3. A list of pairs of integers, specifying the indices of intersecting
  +3. An integer corresponding to the underlying values of quest::WatertightStatus
  + 0: the mesh is watertight (after welding vertices)
  + 1: the mesh is not watertight (has at least one boundary edge)
  + 2: the mesh has some other error, possibly an edge incident in more than
  + two faces
  +4. A list of pairs of integers, specifying the indices of intersecting
  triangles. Each index should be the 0-based index of the triangle in the
  STL file.
  -4. A list of integers, specifying the STL file indices of degenerate triangles.
  +5. A list of integers, specifying the STL file indices of degenerate triangles.
  -The integers on lines 3 and 4 should be separated by whitespace.
  +The integers on lines 4 and 5 should be separated by whitespace.
