Merge remote-tracking branch 'origin/organisational'
Merge branch 'GSOC-Integrator'
Merge branch 'md_RK67' into GSOC-Integrator
Configuration readout changes:
- Pack all the config variables into a struct
- Understand save_nth_mult as float
Re-introduce binary saving option
(not implemented yet)
Also fix icon
Update configuration.ini:
- Options for Integrators separate
- Algorithm select
- Title

Merge branch 'GSOC-Integrator'
Restructure information exchange for integrators:
- integrators receove struct pointer instead of variables
- include information that is needed for PRD calculation
PRD implementation:
- Calculate particle-constant part of PRD in separate function
- Main calculation in calc_accel
- Print out particle radius and add it to the configuration_values struct
- Add CMake option for PRD
Merge branch 'md_PRD' into GSOC-Integrator
-implemented binary conversion for PIntegrator output
- reverse bad fclose displacement
Merge branch 'GSOC-Analyzer'
Hand over some calc_accel arguments using struct pointer
- should be faster
- more compact call and easy access to all configuration values if needed without clutter in the function call
