CPDF constructors and Conv #35
Description
Currently the constructors of the CPDFs only work with mappings that get vectors or matrices as input (mapping(x::AbstractMatrix)::AbstractMatrix same for vector)
This is due to the detect_mapping_variant function that tries to infer which variance type to use. It would be quite tedious to make it work for higher dimension input (as is needed for convs). Should we get rid of this automatic detection?
The specific constructors like CGaussian{Float32,UnitVar} of course till work, as the are not calling detect_mapping_variant.
