/**
 * Marks a template method that returns the {@link arez.ArezContext} instance for component.
 *
 * The method that is annotated with this annotation must also comply with the following constraints:
 * 
 * Must not be annotated with any other arez annotation
 * Must not have any parameters
 * Must be abstract
 * Must not throw any exceptions
 * Must return an instance of {@link arez.ArezContext}.
 * Must be accessible to the class annotated by the {@link ArezComponent} annotation.
 * 
 *   Should not be public as not expected to be invoked outside the component. A warning will be generated but can
 *   be suppressed by the {@link SuppressWarnings} or {@link SuppressArezWarnings} annotations with a key
 *   "Arez:PublicRefMethod". This warning is also suppressed by the annotation processor if it is implementing
 *   an interface method.
 * 
 * 
 *   Should not be protected if in the class annotated with the {@link ArezComponent} annotation as the method is not
 *   expected to be invoked outside the component. A warning will be generated but can be suppressed by the
 *   {@link SuppressWarnings} or {@link SuppressArezWarnings} annotations with a key "Arez:ProtectedMethod".
