 - [ ] In a utility package provide:
-    - [ ] Method to clone an algorithm with user-specified property(hyperparameter)
-          changes, as in `LearnAPI.clone(algorithm, p1=value1, p22=value2, ...)` (since
-          `algorithm` can have any type, can't really overload `Base.replace` without
-          piracy). This will be needed in tuning meta-algorithms. Or should this be in
-          LearnAPI.jl proper, to expose it to all users?
-	- [ ] Methods to facilitate common-use case data interfaces: support simultaneously
-          `fit` data of the form `data = (X, y)` where `X` is table *or* matrix, and
-          `data` a table with target specified by hyperparameter; here `obs` will return a
-          thin wrapping of the matrix of `X`, the target `y`, and the names of all
-          fields. We can have options to make `X` a concrete array or an adjoint,
-          depending on what is more efficient for the algorithm.
