LMDZ.GENERIC: Introduced global1d in callcorrk so that global (using sza) or local (using latitude) 1D simulations can be carried out. Converted all astronomical distances in AU instead of Mkm. This might cause problems with old start files. So added a test in iniorbit. A quite dirty test, but thatll do the job.
