  Helper that lets you pass in concepts where component tuples are expected.
• Entity
  An Entity is a collection of components and associated values.
• EventQuery
  An ECS query that calls a callback when its associated event occurs.
• GeneralQuery
  An ECS query used to find entities in the world.
• GeneralQueryBuilder
  Build a GeneralQuery for the ECS. This is how you find entities in the game world.
• UntrackedChangeQuery
  An ECS query that will call a callback when entities containing components marked with Self::track_change have those components change. This type represents a query that has not had any components marked for tracking yet.

• change_query
  Creates a new ChangeQuery that will find entities that have the specified components that will call its bound function when components marked by ChangeQuery::track_change change.
• despawn_query
  Creates a new EventQuery that will find entities that have the specified components that will call its bound function when an entity with those components are despawned / seen for the last time by this query.
• query
  Creates a new GeneralQueryBuilder that will find entities that have the specified components and can be built to create a GeneralQuery.
• spawn_query
  Creates a new EventQuery that will find entities that have the specified components that will call its bound function when an entity with those components are spawned / seen for the first time by this query.
