This is an example of how I'd like to prevent mass_assignment using cancan.

On this example, the application has 4 roles: admin, owner, employee and contractor.

Each user has 4 fields: login, password, role and company_id.

Admin is the only role capable of creating owners and admins.

Owner can create users, but only of type employee and contractor, and only for their own company. They can not see or otherwise interact in any with users from other companies or admins.

1. Detect when two AABBs are intersecting in a given moment (true/false)
2. Instead of true/false, when they intersect, obtain the minimum displacement vector that would make the first one stop intersecting.
3. Do the same when one of the elements is a circle.
4. Same as before, but the boxes are not axis-aligned any more; they are Oriented Bounding Boxes (OBB)
5. Do the same if one of the boxes is a polygon
6. Now the two shapes can be moving. Given their initial positions, velocities and a time interval, calculate if they collide, and if so, the displacement vector that would move each one "backwards on their trajectory" to the point where they touch but don't intersect any more.
7. Take into account all the special cases: Two objects might already be intersecting. They could also not be intersecting now, but have intersected along their trajectory.
8. Divide the space in subregions so you can test pairs more efficiently. Take into account moving that ob
