An object of class list of length 6.
The helper function constants._hg_
shows (the structure of, optionally)
and returns .hg_constants. 
get_constants simply accesses constants._hg_
The following constants are set here: gravity, properties of water, Poisson's ratios for a typical drained and undrained material, the compressibities of fluid and undrained fluid-saturated rock, atmospheric properties at ATP, and some conversion factors.
This functionality may be replaced in the future with
the options_manager function on CRAN
(in the  new settings package).
