#' Calculate distances to the nearest string
#' 
#' Given a character vector, calculate the distance for each element
#' to the nearest neighbor amongst all the other elements.
#' 
#' @param x A character vector.
#' @param metric A character scalar defining the string distance metric. One
#'   of \code{"hamming"} (default), \code{"hamming_shift"} or
#'   \code{"levenshtein"}.
#' @param nThreads numeric(1), number of threads to use for parallel processing.
#' 
#' @return An integer vector of the same length as \code{x}.
#'

#' Create a conversion table for collapsing similar sequences
#' @param seqs Character vector with nucleotide sequences (or pairs of 
#' sequences concatenated with "_") to be collapsed. The sequences must 
#' all be of the same length.
#' @param scores Numeric vector of "scores" for the sequences. Typically
#' the total read/UMI count. A higher score will be preferred when 
#' deciding which sequence to use as the representative for a group of 
#' collapsed sequences.
#' @param collapseMaxDist Numeric scalar defining the tolerance for collapsing 
#' similar sequences. If the value is in [0, 1), it defines the maximal 
#' Hamming distance in terms of a fraction of sequence length:
#' (\code{round(collapseMaxDist * nchar(sequence))}).
#' A value greater or equal to 1 is rounded and directly used as the maximum
#' allowed Hamming distance. Note that sequences can only be
#' collapsed if they are all of the same length.
#' @param collapseMinScore Numeric scalar, indicating the minimum score 
#' required for a sequence to be considered as a representative for a 
#' group of similar sequences (i.e., to allow other sequences to be 
#' collapsed into it).
#' @param collapseMinRatio Numeric scalar. During collapsing of
#' similar sequences, a low-frequency sequence will be collapsed 
#' with a higher-frequency sequence only if the ratio between the 
#' high-frequency and the low-frequency scores is at least this 
#' high. A value of 0 indicates that no such check is performed.
#' @param verbose Logical scalar, whether to print progress messages.
#' 
#' @return A data.frame with two columns, containing the input sequences 
#' and the representatives for the groups resulting from grouping similar
#' sequences, respectively.
#' 
#' @examples
