Bug 14713: Read LS-Dyna point coordinates properly.

An LS-Dyna simulation may have time-varying nodal coordinates.
In this case, the initial, static coordinates are ignored since
they are overwritten by the deflected coordinates as each timestep
is read. However, it is apparently possible to configure LS-Dyna
not to write the deflected coordinates. In which case, we *must*
read the static coordinate data since that is all that's present.
Do so.
