abstract: High- and low-level functions for processing biogas data and predicting
  biogas production. Molar mass and calculated oxygen demand (COD') can be determined
  from a chemical formula. Measured gas volume can be corrected for water vapor and
  to (possibly user-defined) standard temperature and pressure. Gas quantity can be
  converted between volume, mass, and moles. Gas composition, cumulative production,
  or other variables can be interpolated to a specified time. Cumulative biogas and
  methane production (and rates) can be calculated from raw data obtained using volumetric,
  manometric, gravimetric, or gas density methods for any number of bottles. With
  cumulative methane production data and data on bottle contents, biochemical methane
  potential (BMP) or specific methane production (SMP) can be calculated and summarized,
  including subtraction of the inoculum contribution and normalization by substrate
  mass. Cumulative production and production rates can be summarized in several different
  ways (e.g., omitting normalization) using the same function. Biogas quantity and
  composition can be predicted from substrate composition and additional, optional
  data. Inoculum and substrate mass can be determined for planning BMP experiments.
  Finally, first-order models can be fit to measurements in order to extract estimates
  of ultimate yield and kinetic constants.
