#' Computes the circumcenter of a given triangle, that is, the intersection of its three medians
#'
#' \code{Circumcenter} computes the center of a triangle
#' @param Tri Triangle object, previously created with function \code{CreatePolygon}
#' @param lines Boolean. When \code{lines} = \code{TRUE}, the plot displays the lines that represent the medians of each of the sides of the triangle. If missing, it works as with \code{lines} = \code{FALSE}, so the lines are not displayed
#' @return Vector which contains the xy-coordinates of the circumcenter of the triangle
