In rubens2005/criticalpath: An Implementation of the Critical Path Method

#' criticalpath: Critical Path Method R Implementation
#'
#' `criticalpath` package is an R implementation of the
#' Critical Path Method (CPM). CPM is a method used to estimate
#' the minimum project duration and  determine the amount of scheduling
#' flexibility
#' on the logical network paths within the schedule model. The flexibility is in
#' terms of early start, early finish, late start, late finish, total float and
#' free float. Beside, it permits to quantify the complexity of network diagram
#' through the analysis of topological indicators. Finally, it permits to change
#' the activities duration to perform what-if scenario analysis.
#'
#' With this package, you can calculate the following CPM parameters:
#' - Schedule duration
#' - Early start and finish date of each activity
#' - Late start and finish date of each activity
#' - Critical activities
#' - Critical path
#' - Total float and free float
#' - Gantt Matrix
#' - What-if scenario analysis
#' - Topological indicators
