CHG and NEW:
macros.h: changed name of ISSMBOOT and ISSMEND macros to IssmBoot and IssmEnd. AdolcEdf: moved adolc_edf to src/c/classes and renamed it AdolcEdf. Updated all headers and Makefile.am
accordingly.
Noticed dual existence of objects.h in src/c/classes and src/c/classes/objects! Deleted first one and
fixed references accordingly in bamg and kriging.
Created new EnvironmentInit routine to initialize Petsc and MPI. Updated issm.cpp and kriging.cpp accordingly.
