If the <specific_heat_model> tag is absent from the input file then
used the default constant specific heat.

If the <damage_model> tag is not specified in the input file then use the
default "null" damage model, i.e., no damage parameter is computed.

If the <stability_check> flag is not found in the input file then
default to no check.

If the <melt_temp_mode> tag is missing from the input file use a
constant melt temperature. Clearly, this temperature must be
specified elsewhere in the input file.

A default constant shear modulus modulus is now used if the tag
<shear_modulus_model> is missing from the input file.

The input file now automatically makes the linear EOS the default without
requiring an <equation_of_state> tag. Keep that in mind when you create
your input file.

Truncate the number of Maxwell elements only if time-temperature superposition is turned on.

1) Tested objective rate formulation. Works.
2) Don't allow relaxation times less than the current time step.
Needed when time-temperature superposition is on and
temperature is close to melt temperature.
