Typo in new gitlab-ci

Make sure all install combinations work

Fix for INSTALL_PREFIX

Make that clear for everyone

Dockerfile and .gitlab-ci; remove bindings.*pp files

Complining should work now

Set _n_class for all ModelClassiers

less cluter in the docs

Merge in changes from MPCDF gitlab repo

See merge request sissopp_developers/sissopp!25

File path issue

Python can now just read the sisso.json file

Input object used for SISSOSolver and FeatureSpace Consstructors

See merge request tpurcell/cpp_sisso!31

Tests should now pass

Wrong size used when resizing test values

It must have gotten deleted at some point

Always use task sizes

Step in removing them in general

Minor changes to fix bugs when setting these changes up

Use task_size explictly

So when inputs called then central storage is modified

Not changing it for continuity

Now to clean up

match current name scheme
