/**
 * Bugs often appear in async code when stuff gets disposed, but async operations don't get canceled.
 * This Async helper class solves these issues by tying async code to the lifetime of a disposable object.
 *
 * Usage: Anything class extending from BaseModel can access this helper via this.async. Otherwise create a
 * new instance of the class and remember to call dispose() during your code's dispose handler.
