Detailed Description

template<typename T>
class aureservoir::TrainLS< T >

trains the ESN offline in two steps, as described in Jaeger's "Tutorial on training recurrent neural networks"

1. teacher-forcing/sampling: collects the internal states and desired outputs
2. computes output weights usings LAPACK's least square algorithm
