biomass: Download BWG biomass data set
In SrivastavaLab/bwgbiomass: Generate Biomass From BWG Allometry Data

Download the BWG biomass data from SrivastavaLab/bwgbiomass (https://github.com/SrivastavaLab/bwgbiomass/)

biomass(version = NULL, path = NULL)

biomass_versions(local = TRUE, path = NULL)

biomass_version_current(local = TRUE, path = NULL)

biomass_del(version, path = NULL)

`version`	Version number. The default will load the most recent version on your computer or the most recent version known to the package if you have never downloaded the data before. With `biomass_del`, specifying `version = NULL` will delete all data sets.
`path`	Path to store the data at. If not given, `datastorr` will use `rappdirs` to find the best place to put persistent application data on your system. You can delete the persistent data at any time by running `biomass_del(NULL)` (or `biomass_del(NULL, path)` if you use a different path).
`local`	Logical indicating if local or github versions should be polled. With any luck, `local = FALSE` is a superset of `local = TRUE`. For `biomass_version_current`, if `TRUE`, but there are no local versions, then we do check for the most recent github version.
