#' @details
#' This function creates a definition for a nimbleList.  The \code{types} argument defines the names, types, and dimensions of the elements of the nimbleList.  Elements of nimbleLists can be either basic types (e.g., \code{integer}, \code{double}) or other nimbleList definitions.   
#' The \code{types} argument can be either a series of expressions of the form \code{name = type(dim)}, or a list of \code{\link{nimbleType}} objects.
#' 
#' \code{nimbleList} returns a definition, which can be used to create instances of this type of nimbleList via the \code{new()} member function. 
#' 
#' Definitions can be created in R's general environment or in nimbleFunction setup code.  Instances can be created using the \code{new()} function in R's global environment, in nimbleFunction setup code, or in nimbleFunction run code.  
#' 
#' Instances of \code{nimbleList} definitions can be used as arguments to run code of nimbleFunctions, and as the return type of nimbleFunctions.
