Also use MODFLOW 6 model for consistency?

Wat about partially linked basins? There we overrule the Ribasim input, but only partly replace it with River and Drainage fluxes from MODFLOW 6 right?
| ### Active coupling | ||

| The derivation of active coupling exchanges proceeds largely the same, but also | ||
| locates the nearest subgrid elements: |

Perhaps add: This is needed for the exchange of stages defined at these elements.
| This ensures that Ribasim does not overwrite the exchange flows while running | ||

| Conceptually, it also means that when a basin is coupled, it should generally |

| The second is a more pressing problem, as it will results in a discrepancy | ||
| between the water balances of both models. |

maybe add a comment on how to deal with the second point? The bottom of RIV elements within a basin should never be lower than the lowest waterlevel of the subgrid elements right? This is maybe problematic for the 'downstream' RIV elements?
| ## MODFLOW6 | ||
|
|
||
| No specific files are required. The MODFLOW6 model must contain River or | ||
| Drainage packages which represent the surface water. |

maybe add again: location and bottom elevation need to be consistent with the Ribasim model
This makes a start with the Ribamod imod coupler docs.
I've added a technical section inspired by the MetaMod one. I've also specifically added a section on pre-processing, explicitly mentioning primod.
As mentioned in #41, this is good addition for the other drivers as well.
