einr: Different Functions That I Keep Needing

#' einr: a collection of functions &c.
#'
#' This package collects functions that I have implemented either because I
#' keep needing the same thing over and over or because I was curious about
#' some method that I couldn't find implemented elsewhere. Or because I for some
#' reason wanted to implement it myself even though it was already out there.
