Description

We currently have a single base class from which we inherit all metrics. This makes the code a bit ugly when we call a metric's 'run' function because we have to be flexible enough to accept a variable amount of datasets. So a unary metric's run function still takes an array of datasets even though that array will only have a single dataset in it.
