Please add assemblies to the new Exodus reader

Please add assemblies to the new Exodus reader. Here are details from a user:

--snip-customer-- have recently funded SNL (Greg Sjaardema) to add in assemblies support to the Exodus file format. Greg is about halfway through these modifications which includes updating key Secas tools. I believe Greg has already documented the new features he has added to Exodus. Naturally to make use of this new important capability the pre and post processing tools which support Exodus need to have support added for this assembly capability. Please can you explore if the proposed re-write to the Exodus readers in Paraview could also include adoption of the new assemblies feature in Exodus. The point of contact at SNL for this will be Greg himself. I believe he has about 40 more hours of effort to complete his task with the IOSS before handing over to the STK team to do their bits before the assembly feature can be supported by the wider Sierra codes.
