#' Calculates the Descriptor that Describes the Sum of the Absolute
#' Value of the Difference between Atomic Polarizabilities of
#' All Bonded Atoms in the Molecule
#'
#' This descriptor calculates the sum of the absolute value of the
#' difference between atomic polarizabilities of all bonded atoms
#' in the molecule (including implicit hydrogens) with polarizabilities
#' taken from \url{https://bit.ly/3PvNbhe}.
#' This descriptor assumes 2-centered bonds.
#'
#' @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{bpol}.
