Added separate output of forces due to external potential
Formatting issue in docs from previous commit.
Implemented external Gaussian potentials in planar/cylindrical/spherical geometries for ionic dynamics
Added a few vector and tensor operators needed for CD implementation
Fixed crash in classicalDFT vdwCoupling (bug introduced in D3 implementation)
Elevated CANDLE and SaLSA parameterization warnings to errors, as they lead to failures later if allowed to proceed.
Added reduction of symmetries by mismatched constaints
Updated perlmutter instructions
