This allows for the specification of multiple ZoneGridConnectivity_t
nodes. If these functions are not used, or cg_zconn_write
is called once with a zcname of ZoneGridConnectivity,
then there will be no differences from previous versions of the
CGNS library. However, with multiple ZoneGridConnectivity_t
nodes, there is an implicit current ZoneGridConnectivity_t
node on which subsequent grid connectivity functions will operate,
i.e. cg_conn_read/write or cg_1to1_read/write.
The functions cg_zconn_read and cg_zconn_write
will implicity set the current ZoneGridConnectivity_t
node, while cg_zconn_set explicitly sets it. The functions
cg_nzconns and cg_zconn_get do not change it.
The time-dependent changes to the connectivities may then be recorded
in the ZoneInterativeData_t node as an array of
ZoneGridConnectivityPointers.
