In netDx: Network-based patient classifier

#' Wrapper to write GeneMANIA query file
#'
#' @param qSamps (char) vector of patient IDs in query
#' @param incNets (char) vector of networks to include in this analysis
#' (features/pathway names). Useful for subset-based feature selection
#' @param numReturn (integer) number of patients to return in ranking file
#' @param outFile (char) path to output file
#' @param orgName (char) organism name
#' @return No value. Side effect of writing the query file to
#' \code{outFile}
#' @examples
#' data(pheno)
#' writeQueryFile(pheno$ID[seq_len(5)], 'all',nrow(pheno), 'myquery.txt')
#' @export
