   program morph_line_segment
!
!  Description:
!
!     For a given 3-space line segment, redistribute it to the desired number
!     of points by imposing the relative point distribution of a second 3-space
!     line segment via arc-length based local spline interpolation.
!     This capability facilitates deriving a new capsule generatrix with the
!     same point counts in the various segments as an existing generatrix, which
!     in turn can enable reusing computational flow field solutions as starting
!     guesses for the new geometry.
!
!     See also the earlier redistribute_xy for further line segment operations,
!     as well as the gen_to_grid table-driven utility for treating multiple
!     segments of a generatrix at once, including (now) the same option as is
!     provided by morph_line_segment, the essence of which has been modularized
!     for reuse as a subroutine.

!  History:
!
!     10/03/2022  D.A.Saunders  Initial implementation, to simplify adapting the
!                               gridded generatrix for the Mars SRL capsule
!                               DAC-2.1 as the gridded generatrix for the
!                               similar DAC-2.2.
!     10/27/2023    "     "     The prompts for the two inputs were the same!
!     11/17/2023    "     "     The functionality of this utility has been
!                               modularized as subroutine morph_segment (now in
!                               gridlib) for adding as an option to utility
!                               gen_to_grid, which treats multiple line segments
!                               in a single run.
