Spark has a nice feature that let's you build a Dataset from a case class. We should support this as well.

MleapReflection provides many tools that will be needed for this task.
I am thinking we should support the following conversions:

  1. (case class) -> DefaultLeapFrame w/ 1 row
  2. Seq(case class) -> DefaultLeapFrame w/ n rows
  3. DefaultLeapFrame -> (case class), extracts first row (throw error if more than one?)
  4. DefaultLeapFrame -> Seq(case class), extracts all rows into a Seq of a case class

These conversions should be implicit and included in the MleapSupport trait for easy usage.
