#' Estimation of cold start emissions hourly for the of the week
#'
#' @description \code{emis_cold} emissions are estimated as the product of the
#' vehicles on a road, length of the road, emission factor evaluated at the
#' respective speed. The estimation considers the beta parameter, the fraction of
#' mileage driven
#'
#' @param veh "Vehicles" data-frame or list of "Vehicles" data-frame. Each data-frame
#' as number of columns matching the age distribution of that type of vehicle.
#' The number of rows is equal to the number of streets link
#' @param lkm Length of each link
#' @param ef List of functions of emission factors of vehicular categories
#' @param efcold List of functions of cold start emission factors of vehicular categories
#' @param beta Dataframe with the hourly cold-start distribution to each day
#' of the period. Number of rows are hours and columns are days
#' @param speed Speed data-frame with number of columns as hours
#' @param agemax Age of oldest vehicles for that category
#' @param profile Numerical or dataframe with nrows equal to 24 and ncol 7 day
#' of the week
#' @param simplify Logical; to determine if EmissionsArray should les dimensions,
#' being streets, vehicle categories and hours or default (streets, vehicle
#' categories, hours and days). Default is FALSE to avoid break old code, but
#' the recommendation is that new estimations use this parameter as TRUE
#' @param hour Number of considered hours in estimation
#' @param day Number of considered days in estimation
#' @param array Deprecated! \code{\link{emis_cold}} returns only arrays.
#' When TRUE and veh is not a list, expects a profile as a dataframe producing
#' an array with dimensions (streets x columns x hours x days)
#' @param verbose Logical; To show more information
#' @return EmissionsArray  g/h
