Changes for version 1.2.0:

Minor release for bug fixes:

• General improvements to the adaptive discretization (described in the
  upcoming method paper).
• Better error messages when there is a stack overflow (computation point too
  close to the tesseroid).
• Replace the recursive algorithm with a stack-based algorithm for adaptive
  discretization of tesseroids. This makes the computations faster, specially
  for gravity acceleration and gradient tensor components.
• Divide the tesseroids only along the necessary dimensions. This provides
  speedups when dealing with flattened or elongated tesseroids.
• Speedup tesseroid computations by moving some trigonometric functions out of
  loops.
• BUG fix: Singularities when calculating around a prism. Due to wrong quadrant
  returned by atan2 and log(0) evaluations. Fix by wrapping atan2 in a
  safe_atan2 that corrects the result. log(0) error happened only in cross
  components of the gravity gradient when the computation is aligned with the
  vertices of a certain face (varies for each component. Fix by displacing the
  point a small amount when that happens.
