Expand description

This trait acts as an abstraction over a feature adder, and is primarily used to allow for heterogeneous collections of feature adders in the NDArrayCollector. While it provides methods for adding features and retrieving column headers, it is generally recommended to implement the LengthCheckedFeatureAdder trait instead, which provides compile-time guarantees about the number of features returned.
