This is more for cheat detection than anything, as I don't know when you'd need to check for 'disableCollisionWith' otherwise.
Originally, most cheats (like TSS (Typhoon), Hackmachine, Redengine etc.) would use hideObject on their local player to no-clip through buildings and walls.
This is detected by most major servers now, so they have resorted to using 'disableCollisionWith' to no-clip through walls and such. Yes, we could spectate and find them, but there are times it is very difficult to differentiate between lag and no-clip.
Possibly add a command that would check the state of collision (disabled/enabled) of an object to another. This should go very well with 'disableCollisionWith' and 'enableCollisionWith'.
Maybe return object to object collision(true/false), or just an array of things the object can not collide with.
