Calculate metrics about a lake using just its shape

The R package "httk" provides free, open-source data and models for toxicokinetics. The models are designed to use chemical-specific in vitro (animal free) measurements. The predictions can be used for traditional dosimetry as well as in vivo-in vitro extrapolation (IVIVE). This repository is for reporting bugs and contributing enhancements.
