// .NAME LSDynaMetaData - Read LS-Dyna databases (d3plot)
// .SECTION Description
//    A class to hold metadata about a particular file (such as time steps,
//    the start of state information for each time step, the number of
//    adaptive remeshes, and the large collection of constants that determine
//    the available attributes). It contains an LSDynaFamily instance.
