Berthold Stoeger	23da23a534	core: add N2 and general gas component accessors ... There were helper functions to access O2 and He component fractions. Add another one for N2. Indeed, this can be used in three cases, where N2 was deduced indirectly. Moreover, add a general accessor with a gas_component argument. This will be used by the filter code to filter for gas components. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>	2020-10-03 10:29:15 -07:00
Berthold Stoeger	619d3fb1fd	Cleanup: move gas-functions to own translation unit ... But only functions that operate only on gases. Functions concerning cylinders or dives remain in dive.c or are moved to equipment.c Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>	2019-06-19 13:11:10 -07:00
