Variables associated to shapes

[MartineDeVos]

eWatercycle II: Lumped hydrological models, ungridded surface dynamics models and hydraulic structure control models often have no grid but rather geospatial shapes associated to certain variables. How to deal with this within BMI? Should we seek extensions.

Currently this can be emulated with e.g. a 1D grid where you ignore the "gridiness." More elegant would be to allow for non-grid data stores.
