Managing batch updates through FormSet

[bunop]

Is your feature request related to a problem? Please describe.
This should resolve issues related to batch update, for example fields derived from Foreign Keys, as described in #16

Describe the solution you'd like
Using formset, users should be able to edit multiple form objects in the same time. Ideally we could address issues related to foreign keys (multiple select objects) that the current implementation can't address. Moreover, we could change more than 1 value at time (consider solving location issues with accuracies at the same time). Supporting pagination could solve performance issues. Would be great to select objects to update with no reference to errors of the same type

Describe alternatives you've considered
The current implementation is able to edit the same text based field for objects with same issues. Issues that cannot be solved with batch update should be solved one-by-one
