This PR introduces the following concepts:

  • extension-Pseudometric-Space P: a pseudometric space Q with an isometry i : P → Q;
  • extension-Metric-Space M: a metric space N with an isometry i : M → N;
  • actions on Cauchy approximations of extensions of (pseudo)metric spaces;
  • isometries between extensions of a metric space.

@malarbol this pull request is very large. Is there any possibility of splitting it into smaller chunks, preferrably of less than 1000 lines of code each?
