+// discrete time simulation clock for OpenSteerDemo
+//
+// Keeps track of real clock time and simulation time.  Encapsulates the time
+// API of the underlying operating system.  Can be put in either "as fast as
+// possible" variable time step mode (where simulation time steps are based on
+// real time elapsed between updates), or in fixed "target FPS" mode where the
+// simulation steps are constrained to start on 1/FPS boundaries (e.g. on a 60
+// hertz video game console).  Also handles the notion of "pausing" simulation
+// time.
+//
+// Usage: allocate a clock, set its "paused" or "targetFPS" parameters, then
+// call updateGlobalSimulationClock before each simulation step.
+//
+// 10-04-04 bk:  put everything into the OpenSteer namespace
+// 11-11-03 cwr: another overhaul: support aniamtion mode, switch to

+// Vec3: OpenSteer's generic type for 3d vectors
+//
+// This file defines the class Vec3, which is used throughout OpenSteer to
+// manipulate 3d geometric data.  It includes standard vector operations (like
+// vector addition, subtraction, scale, dot, cross...) and more idiosyncratic
+// utility functions.
+//
+// When integrating OpenSteer into a preexisting 3d application, it may be
+// important to use the 3d vector type of that application.  In that case Vec3
+// can be changed to inherit from the preexisting application' vector type and
+// to match the interface used by OpenSteer to the interface provided by the
+// preexisting 3d vector type.

+
+    This utility is a spatial database which stores objects each of
+    which is associated with a 3d point (a location in a 3d space).
+    The points serve as the "search key" for the associated object.
+    It is intended to efficiently answer "sphere inclusion" queries,
+    also known as range queries: basically questions like:
+
+        Which objects are within a radius R of the location L?
+
+    In this context, "efficiently" means significantly faster than the
+    naive, brute force O(n) testing of all known points.  Additionally
+    it is assumed that the objects move along unpredictable paths, so
+    that extensive preprocessing (for example, constructing a Delaunay
+    triangulation of the point set) may not be practical.
+
+    The implementation is a "bin lattice": a 3d rectangular array of
+    brick-shaped (rectangular parallelepipeds) regions of space.  Each
+    region is represented by a pointer to a (possibly empty) doubly-
+    linked list of objects.  All of these sub-bricks are the same
+    size.  All bricks are aligned with the global coordinate axes.
+
+    Terminology used here: the region of space associated with a bin
+    is called a sub-brick.  The collection of all sub-bricks is called
+    the super-brick.  The super-brick should be specified to surround
+    the region of space in which (almost) all the key-points will
+    exist.  If key-points move outside the super-brick everything will
+    continue to work, but without the speed advantage provided by the
+    spatial subdivision.  For more details about how to specify the
+    super-brick's position, size and subdivisions see lqCreateDatabase
+    below.
+
+    Overview of usage: an application using this facility would first
+    create a database with lqCreateDatabase.  For each client object
+    the application wants to put in the database it creates a
+    lqClientProxy and initializes it with lqInitClientProxy.  When a
+    client object moves, the application calls lqUpdateForNewLocation.
+    To perform a query lqMapOverAllObjectsInLocality is passed an
+    application-supplied call-back function to be applied to all
+    client objects in the locality.  See lqCallBackFunction below for
+    more detail.  The lqFindNearestNeighborWithinRadius function can
+    be used to find a single nearest neighbor using the database.
+
+    Note that "locality query" is also known as neighborhood query,
+    neighborhood search, near neighbor search, and range query.  For
+    additional information on this and related topics see:
+    http://www.red3d.com/cwr/boids/ips.html
+
+    For some description and illustrations of this database in use,
+    see this paper: http://www.red3d.com/cwr/papers/2000/pip.html

+// discrete time simulation clock for OpenSteerDemo
+//
+// Keeps track of real clock time and simulation time.  Encapsulates OS's
+// time API.  Can be put in either "as fast as possible" variable time step
+// mode (where simulation time steps are based on real time elapsed between
+// updates), or in fixed "target FPS" mode where the simulation steps are
+// constrained to start on 1/FPS boundaries (e.g. on a 60 hertz video game
+// console).  Also handles the notion of "pausing" simulation time.
+//
+// Usage: allocate a clock, set its "paused" or "targetFPS" parameters,
+// then call updateGlobalSimulationClock before each simulation step.
