##' Approximate Equality Testing Function
##'
##' This function tests whether two numeric vectors or matrixes are
##' approximately equal to one another, within a specified threshold.
##'
##' Arguments \sQuote{a} and \sQuote{b} must be of the same type,
##' ie. they must be either vectors of equal dimension or matrices of
##' equal dimension. The two arguments are compared element-wise for
##' approximate equality. If the absolute value of the difference of
##' any two values is greater than the threshold, then an error will
##' be thrown.
##'
##' @param a a numeric vector or matrix
##' @param b a numeric vector or matrix
##' @param epsilon a non-negative tolerance threshold

##' Correct Warning Message Function
##'
##' This function tests whether the correct warning message is thrown.
##' Arguments \sQuote{expression} and \sQuote{message} give the expression
##' that generates the warning and the message that is supposed to be generated, respectively.
##'
##' \emph{note}: to test for no warning, set \code{message = NA}.
##'
##'
##' @param expression an R expression that produces a warning
##' @param message a character string with the desired warning message
