lakemorpho: Lake Morphometry Metrics

#' Lake Morphometry in R
#' 
#' Lakemorpho provides a number of functions to calculate a standard suite of 
#' lake morphometry metrics.  Most of the metrics are measurements of the 
#' shape of the lake.  Metrics that rely on depth have traditionally been 
#' calculated with bathymetry data.  In the absence of bathymetry data it is
#' possible to estimate maximum depth from surrounding topography.  Lakemorpho
#' uses this approach to also estimate maximum depth, mean depth, and volume.
