#' @title houseKeep Filtering
#' @description This function filter your matrix count on a specific gene house keepin list
#' @param group, a character string. Two options: sudo or docker, depending to which group the user belongs
#' @param scratch.folder, a character string indicating the path of the scratch folder
#' @param file, a character string indicating the path of the file, with file name and extension included
#' @param geneNameControl, 0 if the matrix has gene name without ENSEMBL geneID. 1 if the gene names is formatted as: ENSMUSG00000000001:Gnai3. If the gene names is made only by ensamble name, scannoByGtf has to be run first.
#' @param houseK, to be described ....
#' @param topCell, to be described ...
#' @param separator, separator used in count file, e.g. '\\t', ','
#' @param logTen, 0 if is raw count, 1 otherwise
#' @author Luca Alessandri , alessandri [dot] luca1991 [at] gmail [dot] com, University of Torino

#' @return return matrix filtered by the best cells that have housekeepin genes most expressed
