Added new equation of state for ICE materials: HardSphereGas

A SCIRun/src/Packages/Uintah/CCA/Components/ICE/EOS/HardSphereGas.cc

useage in the UPS file (<ICE> section):

<EOS type="hard_sphere_gas">
<b> 1.4e-3 </b>
</EOS>

This EOS is a simple extension of the ideal gas EOS, but accounts for
the finite volume occupied by the molecules themselves, so causes the
computed pressure to be greater at high densities. The EOS is given by:

P(V-b) = RT (where b = specific volume of molecules)

Typical value for b is 1.4e-3 m^3/kg (e.g., for N2 or CO).
