In ftrCOOL: Feature Extraction from Biological Sequences

#' Read Directory of Torsion predicted files (readTorsionDir)
#'
#' This function reads a directory that contains the output files of SPINE-X.
#' It gets the directory path as the input and returns a list of vectors. Each vector includes the phi and psi angle
#' of the amino acids of the sequence.
#'
#'
#' @param dirPath The path of the directory which contains all output files of SPINE-X. Each file belongs to a sequence.
#'
#'
#' @return returns a list of vectors with all the predicted phi and psi angles for each amino acid. The length of the
#' list is the number of files(sequences) and the length of each vector is (2(phi-psi)*length sequence(i)).
