2023-05-05 ECA Sprint Model 1: ECA working with VBO

[ECA working with VBO](https://ecaguide.org/library/simple/eca_working_with_vbo/) In this video, we've built this model to show how ECA can work together with views bulk operations. That means that one can build any number of operations in ECA that can be made available to VBO to be executed on any number of selected rows in a view.
