* I discovered a header file had #define NDEBUG 1. It was confined to
  Poincare operator and plot but out of caution I removed that line anyways.
* I fixed a bug in Silo reader causing a crash whenever a ucdmesh with
  no zonelist, facelist, edgelist or phzonelist was defined. I made the
  reader treat it like a point mesh. This is #2111 in the tracker.
* I fixed a bug in Namescheme that was terminating an inner loop correctly
  and causing a valgrind error.
* I fixed a bug in Namescheme_test where a namescheme being tested was mal-formed.
* I fixed a problem with avtMaterial constructor for the case of full zonal
  arrays for the volume fractions. The constructor wasn't robust in the presence
  of numerically likely but nonehtless mal-formed volume fractions (e.g. one
  material has frac>=1 and still another >0. The logic caused that case to
  skip an entry in the mix arrays leaving it uninitialized. Later in 
  avtUnstructuredDomainBoundaries::ExchangeMixedMaterials, it would cause
  a SEGV.
* I fixed a valgrind error in avtUnstructuredDomainBoundaries::ExchangeMixedMaterials
  where several memcpy calls were overrunning the end of the source buffers.
* I fixed a problem where Exodus plugin's auto-expression logic caused a SEGV if
  a candidate vector had fewer than 3 components.
