# inorm - IDF Visualization Function for Normal Distribution
# ------------------------------------------------------------------------------
# The inorm R function visualizes the normal idf evaluated at a provided
# uniform(0,1) u. This will graph the idf in action (via dashed lines back across
# the cdf). Note that the u argument can be a scalar or vector. If a vector,
# multiple dashed lines will be displayed, and the return type will be a vector.
# The function also gives the option of displaying a histogram of the variates
# generated, with theoretical normal superimposed.
