add path to current documentation

add description how to get a specific tagged version

Fix bugs in start scripts

MAgPIE coupling: automatically start SSP2-Base and SSP2-NDC with QOS priority since all other runs depend on them.

* Enable prepare_and_run.R to restart fixed runs (https://github.com/remindmodel/remind/issues/112)
* Enable start.R to restart non-optimal runs

Refactor gitignore file

bugfix: parameter was too heavy

Reintroduce biomass bound. Further improvements (not relevant for the model behaviour)

Change the reference scenario (for calculating the BECCS bound, see previous commit) from input_ref.gdx to the values of the own previous nash iteration.

bugfix: on parameter was filled with values for all combinations possible instead of only the necessary ones

Reintroduce bound on biomass relative to reference scenario to prevent regions with large carbon storage potential from deploying BECCS in tight policy cases only to produce negative emissions rather then generating energy.

Tutorials: add missing dependencies to list of packages that are required to run REMIND.

add Zenodo DOI to README.md

updated version number

Harmonization of UE passenger share of HDV transport

target for passenger share of HDV transport.

Harmonize tutorial text with documentation

Small changes for NDC, NPi and ENGAGE scenarios

Add newest member's names to Citation files

This section exists in the documentation as well, and has been rewritten. It is now simply copied to the tutorial text, here, as well.

change version of gdx being used for NDC target calculation (now input_bau.gdx) so that correct NDC targets are also calculated for non-SSP2 pathways

Add Zenodo JSON
