Set MeV as a base unit for numerical convenience
Set default scale factor integration step smaller and initial aT=1
Rebuild GRID too if initial parameters change
Logger documentation
Try different integrators
Actually, K1 and K2 are index-dependent!
Update docs, do some refactoring
Vectorize distribution functions outside the class definition – or it simply won't work!
Save also aT inside the particle species
Refactor the function interpolation routine
Refactor a bit
Some testing and plotting code
Fix – serious error
Interpolate collision integral too
Use aT
Use save aT value for corresponding equilibrium distribution calculation
TODO
Test update
One more test
Create distribution interpolation test
