This PR implements the dyn_init subroutine, which is responsible for initializing MPAS dynamical core by one of the following methods:
Setting analytic initial condition.
Reading initial condition from a file.
Restarting from a file.
This should be the last step of MPAS dynamical core initialization. After this PR, MPAS dynamical core is ready for time integration.
Implementation notes:
More elaborate error checking for the allocation of constituents.
Support for deferring the definition of constituents until run-time. There are no longer assumptions about the index order or position of constituents.
Accessor functions/subroutines for querying:
Local mesh dimensions.
Constituent names and indexes.
Mapping between constituent indexes and MPAS scalar indexes.
Enhancements that enable constructing an arbitrary list of variables to input/output data to/from MPAS dynamical core.
Enhancements and fixes for handling ordinary variables and variable arrays during input.
Finish MPAS dynamical core initialization.
