Compute the output vector metadata only from the input features.
Compute the output vector metadata only from the input features. Vectorizers use this to derive the full vector, including pivot columns or indicator features.

Base class for vectorizing OPMap[A] features. Individual vectorizers for different feature types need to implement the getFillByKey function (which calculates any fill values that differ by key - means, modes, etc.) and the makeModel function (which specifies which type of model will be returned).
