Takes a writable reference to a mesh object. This is the constructor required to read a mesh. The optional parameter binary
can be used to switch between ASCII (false

Return/set the precision to use when writing ASCII files.
By default we use numeric_limits<Real>::max_digits10, which should be enough to write out to ASCII and get the exact same Real back when reading in.

Used to remove a checkpoint directory and its corresponding files.
This effectively undoes all the work done be calls to write(...). For example, if a checkpoint configuration was written via:
unsigned int n_splits = 42; std::unique_ptr<CheckpointIO> cp = split_mesh(my_mesh, n_splits); // ... cp->write("foo.cpr");
then you could remove all the corresponding created files/dirs by:
CheckpointIO::cleanup(my_mesh, n_splits);
Or for cases where the split configuration was determined automatically (e.g. via number of running procs with distributed/parallel mesh), then you could:
CheckpointIO::cleanup(your_mesh, your_mesh.comm().size());
Other remaining checkpoint split configurations for the mesh are left unmodified.

This method implements reading a mesh from a specified file.
If the mesh has been split for running on several processors, input_name should simply be the name of the mesh split directory without the "-split[n]" suffix. The number of splits will be determined automatically by the number of processes being used for the mesh at the time of reading.

This method implements writing a mesh to a specified file.
If the mesh has been split for running on several processors, this will create a subdirectory named "[name]-split[n]" where name is the given name argument and n is the number of processors the mesh is split for running on. For example:
unsigned int n_splits = 42; std::unique_ptr<CheckpointIO> cp = split_mesh(my_mesh, n_splits); // ... cp->write("foo.cpr");
would create a directory named "foo.cpr-split42".
Implements libMesh::MeshOutput< MeshBase >.

This method may be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.
If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.
Reimplemented in libMesh::Nemesis_IO.

This method should be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it directly uses EquationSystems current_local_solution vectors to look up nodal values.
If not implemented, reorders the solutions into a nodal-only NumericVector and calls the above version of this function.
