If we calculate the nullspace of the matrix
`a=mutableMatrix{{0.0,1.0,2.0,3.0,0.0,0.0,0.0,0.0},{4.0,3.0,2.0,1.0,0.0,0.0,0.0,0.0},{0.0,0.0,0.0,0.0,1.0,2.0,3.0,4.0},{0.0,0.0,0.0,0.0,3.0,2.0,1.0,0.0}}`

We currently assume matrices are square and don't deal with overdetermined/underdetermined. Certainly lu can work, as Avi Kulkarni and wbhart found out.

Looking into an issue where after a restart the number of iterations for a Stokes solve differs greatly, I noticed that the rhs and the matrix of the advection solves also differ between a restarted t…

We recently switched from PDB > CIF with two main motivations:
- store metrics (like pLDDT) without abusing b-factor, and hopefully store pairwise interaction metrics as well (PAE etc)
- better c…
