Module bundle 

Bundles: the set of components an entity is spawned with.

A bundle is either a DynamicBundle, which the crate::bundle! macro writes, or a type of the caller’s own that implements Bundle over its components. It is not a tuple: every 'static type is a component, tuples included, so a bare (a, b) handed to spawn names one component rather than two. Writing bundle![a, b] is what names two.

The macro takes its items one at a time and each item is one component, so a parenthesised item is a tuple component rather than a list to unpack: a bundle only spreads when it is written as ..value.

The same component cannot appear twice in a bundle; spawning with duplicates panics.
