Reorganizing physics/dynamics interface:
- what is related to dynamics-physics interface is now in a seperate directory: dynlmdz_phy* for physics in phy*
- 1d model and related dependencies (including a couple from "dynamics", set up as symbolic links) is now in subdirectory "dyn1d" of phy*.
- "bibio" directory is now "misc" and should only contain autonomous utilities.
- "cosp" is now a subdirectory of phylmd.
