#'@description The \dQuote{Vertical} classes are building blocks used to create other classes
#'in this package. As such, it is most likely to be useful for developers
#'who wish to code their own calibration/simulation routines.

#'@description The \dQuote{VertBargBertLogit} class has the information for a Vertical Supply Chain with Logit demand and a downstream Nash-Bertrand Pricing game.

#'@description The \dQuote{VertBarg2ndLogit} class has the information fora Vertical Supply Chain with Logit demand and a downstream 2nd Score Auction.
#'@slot up an instance of \dQuote{Bargaining} class.
#'@slot down For  \dQuote{VertBargBertLogit}, an instance of  \dQuote{Logit} class.For  \dQuote{VertBarg2ndLogit}, an instance of  \dQuote{Auction2ndLogit} class.
#'@slot constrain  A length 1 character vector equal to "global", "pair", "wholesaler", or "retailer.
