Clean up warnings
There are numerous warnings coming out of the interpolant tests such as:
testInterp4D.cpp.cu(236): warning: variable "d2x0x1" was declared but never referenced
These should be cleaned up.
I am also seeing warnings on cuda builds like this:
/scratch/local/aurora_fast/jcs/TabProps_jcs_mac/./tabprops/LagrangeInterpolant_Poly.h(357): warning: inline qualifier ignored for "global" function
/scratch/local/aurora_fast/jcs/TabProps_jcs_mac/./tabprops/LagrangeInterpolant_Poly.h(422): warning: inline qualifier ignored for "global" function
/scratch/local/aurora_fast/jcs/TabProps_jcs_mac/./tabprops/LagrangeInterpolant_Poly.h(488): warning: inline qualifier ignored for "global" function
/scratch/local/aurora_fast/jcs/TabProps_jcs_mac/./tabprops/LagrangeInterpolant_Poly.h(570): warning: inline qualifier ignored for "global" function
Note that these warnings are showing up on aurora (gcc 4.9.3)
