For now only strings are accepted as the measures parameter in GridSearchCV, RandomizedSearchCV, and cross_validate. It's thus impossible to use those with measures that take specific parameters as input (e.g. #156 ), or to use custom measures.

We should then accept callables in addition to strings.

Each callable should only take the predictions parameter. In order to handle measur

We should add type aliases like type UnitVector3<N> = Unit<Matrix<N, U3, U1, Owned<N, U3, U1>>>; to simplify their uses, e.g., in SIMD code: UnitVector3::from([v1, v2, v3, v4]).

Description:

Add a health check (/health) endpoint that allows orchestration tools to see if a component is up and running.
