#'
#' @param .data A tidy SingleCellExperiment object
#' @param features A vector of feature identifiers to join
#' @param all If TRUE return all

#' Efficiently bind multiple data frames by row and column
#'
#' This is an efficient implementation of the common pattern of
#' `do.call(rbind, dfs)` or `do.call(cbind, dfs)` for binding many
#' data frames into one.
#'
#' The output of `bind_rows()` will contain a column if that column
#' appears in any of the inputs.
#'
#' @param ... Data frames to combine.
#'
#'   Each argument can either be a data frame, a list that could be a data
#'   frame, or a list of data frames.
#'
#'   When row-binding, columns are matched by name, and any missing
#'   columns will be filled with NA.
#'
#'   When column-binding, rows are matched by position, so all data
#'   frames must have the same number of rows. To match by value, not
#'   position, see mutate-joins.
#' @param .id Data frame identifier.
#'
#'   When `.id` is supplied, a new column of identifiers is
#'   created to link each row to its original data frame. The labels
#'   are taken from the named arguments to `bind_rows()`. When a
#'   list of data frames is supplied, the labels are taken from the
#'   names of the list. If no names are found a numeric sequence is
#'   used instead.
#' @param add.cell.ids from Seurat 3.0 A character vector of length(x = c(x, y)). Appends the corresponding values to the start of each objects' cell names.
#'
#' @return `bind_rows()` and `bind_cols()` return the same type as
#'   the first input, either a data frame, `tbl_df`, or `grouped_df`.
