Support for ordinary arrays

• configure now checks compiler for correct bounds of ordinary (i.e. non-allocatable) assumed-rank arrays and modifies code, if needed.
• transformation supports offsets.
• bandwidth test supports a single variable.
• check for correct libtool version.

Bugfix

• Fixed name change for distribution of halo exchanges (now it's again call dist%halo..)

Ready for more

• Derived type decomposition now replaced with types composition and distribution.
• Renamed derived type halo to parcel.

Reduce the overhead!

• Added functions to disable and enable checking of array bounds (default is enabled): gabriel_disable_checking, gabriel_enable_checking, gabriel_set_checking

Bugfix release

• Bug fixed when no periodicity is required.

Initial release

This library provides convenience functions for Fortran codes using MPI to do computations on regular grids. It simplifies the implementation of halo exchanges and transformations to only two routines: one to setup and one to transfer data.
