TMVA Classification Example Using a Recurrent Neural Network

This is an example of using a RNN in TMVA. We do classification using a toy time dependent data set that is generated when running this example macro

Running with nthreads = 4
--- RNNClassification : Using input file: time_data_t10_d30.root
DataSetInfo : [dataset] : Added class "Signal"
: Add Tree sgn of type Signal with 2000 events
DataSetInfo : [dataset] : Added class "Background"
: Add Tree bkg of type Background with 2000 events

# TMVA Classification Example Using a Recurrent Neural Network
This is an example of using a RNN in TMVA.
We do the classification using a toy data set containing a time series of data sample ntimes
and with dimension ndim that is generated when running the provided function `MakeTimeData (nevents, ntime, ndim)`
