#' consensusSeekeR: Detection of consensus peak regions inside a group of
#' experiments using narrowPeak files
#'
#' This package compares positions and ranges data from multiple experiments
#' to extract common consensus regions. The size of the analyzed region is
#' adjustable as well as the number of experiments in which a peak must be
#' detected to mark a potential region as a consensus peak region.
