#pragma mark - Singleton Asserts
// The "singleton asserts" can be used to ensure
// that we only create a singleton once.
//
// The simplest way to use them is the OWSSingletonAssert() macro.
// It is intended to be used inside the singleton's initializer.
//
// If, however, a singleton has multiple possible initializers,
// you need to:
//
// 1. Use OWSSingletonAssertFlag() outside the class definition.
// 2. Use OWSSingletonAssertInit() in each initializer.
