Fixed Ascii vs. Exodus restart discrepancy bug that was showing up for FELIX problems
with non-contiguous Global IDs.  First 4 and last 4 columns of eles files had to be swapped
to be consistent with the Exodus convention.

LCM: fix a few mroe bugs related to temperature dependent Constitutive Params

NOTE: The equation for Linear temperature dependence goes as:

P += dPdT * ( temperature - ref_temperature )

So if you have an inverse relationship between P and T dPdT should be negative.
Also, you need to set the reference temperature for each parameter. Thus there
should be a reference temperature defined for each temperature dependent
parameter.

For example, for two temperatuer dependent parameters:

      <ParameterList name="Yield Strength">
        <Parameter name="Yield Strength Type" type="string" value="Constant"/>
        <Parameter name="Value" type="double" value="450.0"/>
        <Parameter name="Reference Temperature" type="double" value="293.0"/>
        <Parameter name="Linear Temperature Coefficient" type="double" value="-0.002"/>
      </ParameterList>
      <ParameterList name="Elastic Modulus">
        <Parameter name="Elastic Modulus Type" type="string" value="Constant"/>
        <Parameter name="Value" type="double" value="205.7e3"/>
        <Parameter name="Reference Temperature" type="double" value="290.0"/>
        <Parameter name="Linear Temperature Coefficient" type="double" value="-0.01"/>
      </ParameterList>
Added AERAS project and first toy problem.

AERAS is the code name for the new Atmosphere Dynamics LDRD

* Added ENABLE_AERAS configure option to toggle ALBANY_AERAS #define
* Added src/AERAS directory with problems and evaluators subdirs
* Added AERAS::EulerProblem class and hooked it up in Problem Factory
* Added AERAS::EulerResid evaluator to implement a PDE that resembles flow
* Added examples/AERAS test directory with Euler test prob
* Added doc/do-cmake-aeras example cmake script
Added temperature field to Ascii mesh reader.

LCM: More refactor of topology (WIP)
Misc test and code cleanup.

1. Fixed time output in vtk files.
2. Cleaned up test outout on Heat2DMMCylWithSource and
   SteadyHeat1DEB.
3. Built helper class for CellTopo for eventual element enrichment.
4. Add error for unsupported side topology in PHAL_Neumann.
5. Ignore dimension template warnings in TmplSTKMesh with clang.
Convert to case insensitive compare for side topology error checking in PHAL_Neumann BCs.
