#' Descriptor that Calculates the Number of Atoms in the Longest Aliphatic Chain
#'
#' This descriptor calculates the number of atoms in the longest aliphatic chain.
#'
#' @param molecules Parsed molucule object.
#' @param silent Logical. Whether the calculating process
#' should be shown or not, default is \code{TRUE}.
#'
#' @return A data frame, each row represents one of the molecules,
#' each column represents one feature.
#' This function returns one column named \code{nAtomLAC}.
