entities are the things that do something ( move , emit light ...)
there are 2 kinds of entities "point" and "brush-based'
point entities do their job in a single point ( lights ,weapons on the ground ..)
brush entities do their job in an area of a brush (a brush is an object , a 3d shape , whatever is solid and just sits there )
brush entities are made from making a brush and transforming it into an entity (Ctrl + T)
they are the entities with the "FunC_" in front
