<BLOCKQUOTE>This class enable to read sequences (hence inherits from <TT>SeqDataSet</TT>)
from the classical Torch data format. Depending on the options, it
can read one sequence per line (thus having sequences of size 1)
or one sequence per file (then having sequences of size the size of
the files). One can specify the number of inputs, observations and
targets in the given file.
