#' Devolopment of genetic/breeding value
#'
#' Function to plot genetic/breeding values for multiple generation/cohorts
#' @param population population list
#' @param database Groups of individuals to consider for the export
#' @param gen Quick-insert for database (vector of all generations to export)
#' @param cohorts Quick-insert for database (vector of names of cohorts to export)
#' @param json If TRUE extract which cohorts to plot according to the json-file used in json.simulation
#' @param ibd.obs Number of Individual pairs to sample for IBD estimation
#' @param hbd.obs Number of Individuals to sample for HBD estimation
#' @param display.cohort.name Set TRUE to display the name of the cohort in the x-axis
#' @param display.time.point Set TRUE to use time point of generated to sort groups
#' @param equal.spacing Equal distance between groups (independent of time.point)
#' @param time_reorder Set TRUE to order cohorts according to the time point of generation
#' @param display.hbd Set to TRUE to also display HBD in plot
#' @examples
#' data(ex_pop)
#' kinship.development(ex_pop,gen=1:5)
#' @return Estimated of avg. kinship/inbreeding based on IBD/HBD
#' @export
