Evaluating the syntax for meta ini files
Some ideas for the syntax of meta ini files:
already implemented
__name = poisson_{gridtype}_{permeability}
gridtype =grid= yasp, ug
level =grid= 5, 3
permeability == scalar, tensor
treat second token as assignment operator regardless of its shape
__name = poisson_{gridtype}_{permeability}
gridtype gridvariation yasp, ug
level gridvariation 5, 3
permeability permtype scalar, tensor
timos proposal
__name = poisson_{gridtype}_{permeability}
gridtype = (yasp, ug) grid
level = (5, 3) grid
permeability = (scalar, tensor)
... is technically possible without brackets
__name = poisson_{gridtype}_{permeability}
gridtype = yasp, ug grid
level = 5, 3 grid
permeability = scalar, tensor
