      Description

      In SERVER-37831 find projection execution has been separated into three classes: one with the full implementation and two with different fast paths. We should create corresponding QuerySolutionNode subclasses because we want a one-to-one correspondence between PlanStages subclesses and these. Intuitively we want the planner to have direct knowledge of which implementation it is choosing.
