docs: Tests if a particular fractional coord is within a fractional coord_list.
  
      Args:
          fcoord_list: List of fractional coords to test
          fcoord: A specific fractional coord to test.
          atol: Absolute tolerance. Defaults to 1e-8.
  
      Returns:
          True if coord is in the coord list.
