#'@title Display node transition with specified treatment plan or exposure
#'@description Calculate the number of subjects (proportion) assigned to different sub-nodes after specified treatment plan or exposure in certain node.
#'@usage EvolutionAfterTreatment(
#'df,
#'treepoint,
#'mytree,
#'source,
#'treatment
#')
#'@param df "data" in the return result of the \code{survivalpath()} function
#'@param treepoint list object;Specify the node for drawing the KM curve, the node number is displayed in the survival path tree graph.
#'@param mytree "tree" in the return result of the \code{survivalpath()} function
#'@param source Data.frame of time slice data, which could be returned by \code{timedivision()}
#'@param treatment Factor variable in the source data.frame. This argument is to specify the intervention or exposure that of interest at a specific node.
#'@return A data.frame object, whose rows and columns represents the number of subjects in the sub-nodes (in the next time slice) and treatment plan, respectively.
