The appending capability should already be supported, but it's not
turned on by default.
So:
for (unsigned int i_step = 0; i_step<100; i_step)
{
ExodusII_IO exio(mesh);
exio.append(true);
exio.write_timestep("transient_data.exo", eq_sys, i, i*.01);
}
*should* work, but I'm not sure if we want to encourage this repeated
creation/deletion pattern when it's not necessary.
