extend shared sets with ghost entities After ghosting, ghost entities do not have yet information about the material set, partition set, Neumann or Dirichlet set they could belong to This method will assign ghosted entities to the those special entity sets In some case we might even have to create those sets, if they do not exist yet on the local processor
The special entity sets all have an unique identifier, in a form of an integer tag to the set. The shared sets data is not used, because we do not use the geometry sets, as they are not uniquely identified

Exchange ghost cells with neighboring procs Neighboring processors are those sharing an interface with this processor. All entities of dimension ghost_dim within num_layers of interface, measured going through bridge_dim, are exchanged. See MeshTopoUtil::get_bridge_adjacencies for description of bridge adjacencies. If wait_all is false and store_remote_handles is true, MPI_Request objects are available in the sendReqs[2*MAX_SHARING_PROCS] member array, with inactive requests marked as MPI_REQUEST_NULL. If store_remote_handles or wait_all is false, this function returns after all entities have been received and processed.

| bridge_dim | Dimension of entities used to measure layers from interface |
| num_layers | Number of layers of ghosts requested |

Serialize entity tag data.
This function operates in two passes. The first phase, specified by 'just_count == true' calculates the necessary buffer size for the serialized data. The second phase writes the actual binary serialized representation of the data to the passed buffer.
First two arguments are not used. (Legacy interface?)
| entities | NOT USED |
| start_rit | NOT USED |
| whole_range | Should be the union of the sets of entities for which tag values are to be serialized. Also specifies ordering for indexes for tag values and serves as the superset from which to compose entity lists from individual tags if just_count and all_possible_tags are both true. |
| buff_ptr | Buffer into which to write binary serialized data |
| count | Output: The size of the serialized data is added to this parameter. NOTE: Should probably initialize to zero before calling. |
| just_count | If true, just calculate the buffer size required to hold the serialized data. Will also append to 'all_tags' and 'tag_ranges' if all_possible_tags == true. |
| store_handles | The data for each tag is preceded by a list of EntityHandles designating the entity each of the subsequent tag values corresponds to. This value may be one of: 1) If store_handles == false: An invalid handle composed of {MBMAXTYPE,idx}, where idx is the position of the entity in "whole_range". 2) If store_hanldes == true and a valid remote handle exists, the remote handle. 3) If store_hanldes == true and no valid remote handle is defined for the entity, the same as 1). |
| to_proc | If 'store_handles' is true, the processor rank for which to store the corresponding remote entity handles. |
| all_tags | List of tags to write |
