code: def calc_point_dist(vsA, entryA):
      
      chi_diffs = vsA - entryA
      val = ((chi_diffs)*(chi_diffs)).sum()
      return val
docs: This function is used to determine the distance between two points.
  
      Parameters
      ----------
      vsA : list or numpy.array or similar
          An array of point 1's position in the \chi_i coordinate system
      entryA : list or numpy.array or similar
          An array of point 2's position in the \chi_i coordinate system
      MMdistA : float
          The minimal mismatch allowed between the points
  
      Returns
      --------
      val : float
          The metric distance between the two points.
