pub struct TemplateContext<'a, 'w> {
    pub entity: &'a mut EntityWorldMut<'w>,
    pub entity_references: &'a mut SceneEntityReferences,
}

entity: &'a mut EntityWorldMut<'w>

The current entity the template is being applied to

entity_references: &'a mut SceneEntityReferences

A mapping of SceneEntityReference to Entity used for resolving #Name entity references
