Defines functions stretch_to_unitspheroid

Documented in stretch_to_unitspheroid

#' Stretches the ellipsoid (hellip) to the unit spheroid of the same dimension.  Both the input ellipsoid and unit spheroid are centered at the origin.
#'
#' @param hellip The original shape to be stretched
#' @return A list of: hellip1 - a new unit spheroid, mapped from the ellipsoid and tfm - transformation matrix that creates the stretching
