////////////////////////////////////////////////////////////////////
// Class : AsyncTaskManager
// Description : A class to manage a loose queue of isolated tasks,
// which can be performed by a background thread (in
// particular, for instance, loading a model file).
// which can be performed either synchronously (in the
// foreground thread) or asynchronously (by a background
// thread).
//
// The AsyncTaskManager will spawn a specified number of
// threads (possibly 0) to serve the tasks. If there
// are no threads, you must call poll() from time to
// time to serve the tasks in the main thread.
// The AsyncTaskManager is actually a collection of
// AsyncTaskChains, each of which maintains a list of
// tasks. Each chain can be either foreground or
// background (it may run only in the main thread, or it
// may be serviced by one or more background threads).
// See AsyncTaskChain for more information.
//
// Each task will run exactly once each epoch. Beyond
// that, the tasks' sort and priority values control the
// order in which they are run: tasks are run in
// increasing order by sort value, and within the same
// sort value, they are run roughly in decreasing order
// by priority value, with some exceptions for
// parallelism. Tasks with different sort values are
// never run in parallel together, but tasks with
// different priority values might be (if there is more
// than one thread).
// If you do not require background processing, it is
// perfectly acceptable to create only one
// AsyncTaskChain, which runs in the main thread. This
// is a common configuration.
