  Projection
A projection from a Sheet into a ProjectionSheet.
  CFProjection
A projection composed of ConnectionFields from a Sheet into a ProjectionSheet.
  CFPOF_SharedWeight
CFPOutputFn for use with SharedWeightCFProjections.
  SharedWeightCF
  SharedWeightCFProjection
A Projection with a single set of weights, shared by all units.
  LeakyCFProjection
A projection that has a decay_rate parameter so that incoming input is decayed over time as x(t) = input + x(t-1)*exp(-decay_rate), and then the weighted sum of x(t) is calculated.
  ScaledCFProjection
Allows scaling of activity based on a specified target average activity.
  OneToOneProjection
A projection that has at most one input connection for each unit.
