Move stuck code out of main pathing function so we can add logging easily later

400 ms is far too aggressive for normal game play
Set to 10 ms to hopefully not get in the way of legitimate game play

Also, why do we even do this? As far as I can tell, we need this to be
less than the users ping to not cause issues. What are the actual
reasons we do this and what can we do differently to solve them?

 EQEMu Changelog (Started on Sept 24, 2003 15:50)
 -------------------------------------------------------
+
+== 7/14/2017 ==
+Akkadius: HP Update tuning - HP Updates are now forced when a client is targeted
+Akkadius: Client position updates should be smoother (granted the client has a good connection)
+	- Clients should also no longer randomly disappear 
+
+== 7/11/2017 ==
+Akkadius: Raid/Group/XTarget HP/Mana/Endurance updates now only send when percentage changes
+Akkadius: Raid/Group Mana/Endurance updates should now update real-time once again
+Akkadius: Fixed an issue with clients looking like they are 'skipping' when they are moving in view of another client
+Akkadius: Fixed an issue with NPC's who are ghosted in plain view of a client when they are not really there
+
+== 7/9/2017 ==
+Akkadius: Fix HP update issues, rework logic for more accurate HP updates
+Akkadius: Massive reductions in unnecessary network traffic especially during high spam combat fights
+	- HP Updates now only send to others when HP percentage changes (0-100%)
+		- HP Updates were sending excessively even during idle zones when HP wasn't changing at all
+	- Attack animations now only send once per second versus up to a hundred times a second per Mob/Client
+	- 17,000 OP_ClientUpdate packets per second have been observed in combat scenarios, some of the major culprits have been
+		throttled without affecting what the client should see
+	- Before and After packet differences under similar load/tests (Packets per second)
+		- 7,000 - 8,000 	OP_Animation pps	After: 600-800 pps
+		- 13,0000 - 17,000 	OP_MobHealth pps	After: 1-10 pps
+		- 15,0000 - 20,000 	OP_ClientUpdate pps	After: 500-1,000 pps
+	- Packet reports from a 46 client test here:
+		https://gist.github.com/Akkadius/28b7ad2fdd82bdd15ea737c68f404346
+	- Servers who use Marquee HP updates will also recieve far less packet spam as they will only be sent when HP changes
+
+== 7/1/2017 ==
+Akkadius: Resolve issues with NPC's hopping to the ceiling in small corridors
+Akkadius: Improved grounding issues with NPC's during combat
+Akkadius: Improved scenarios where NPC's need to be dragged out of the ground - they should correct themselves far more consistently
+	- Scenarios where an NPC is coming up from the bottom floor, or from the top floor, they will correct much better
+	- A video of these tests can be found here: https://www.youtube.com/watch?v=HtC7bVNM7ZQ&feature=youtu.be
+
 == 6/28/2017 ==
 Akkadius: Fixed issues with Z correctness when NPCs are pathing on normal grids
 Akkadius: Fixed issues with Z correctness when NPCs are engaged with players following

+4.0.0 - 2017-06-27
+------------------
+
+* Removed old compatibility headers ``cppformat/*.h`` and CMake options (`#527 <https://github.com/pull/527>`_). Thanks `@maddinat0r (Alex Martin) <https://github.com/maddinat0r>`_.
+
+* Added ``string.h`` containing ``fmt::to_string()`` as alternative to ``std::to_string()`` as well as other string writer functionality (`#326 <https://github.com/fmtlib/fmt/issues/326>`_ and `#441 <https://github.com/fmtlib/fmt/pull/441>`_):
+
+  .. code:: c++
+
+    #include "fmt/string.h"
+  
+    std::string answer = fmt::to_string(42);
+
+  Thanks to `@glebov-andrey (Andrey Glebov) <https://github.com/glebov-andrey>`_.
+
+* Moved ``fmt::printf()`` to new ``printf.h`` header and allowed ``%s`` as generic specifier (`#453 <https://github.com/fmtlib/fmt/pull/453>`_), made ``%.f`` more conformant to regular ``printf()`` (`#490 <https://github.com/fmtlib/fmt/pull/490>`_), added custom writer support (`#476 <https://github.com/fmtlib/fmt/issues/476>`_) and implemented missing custom argument formatting (`#339 <https://github.com/fmtlib/fmt/pull/339>`_ and `#340 <https://github.com/fmtlib/fmt/pull/340>`_):
+
+  .. code:: c++
+
+    #include "fmt/printf.h"
+ 
+    // %s format specifier can be used with any argument type.
+    fmt::printf("%s", 42);
+
+  Thanks `@mojoBrendan <https://github.com/mojoBrendan>`_, `@manylegged (Arthur Danskin) <https://github.com/manylegged>`_ and `@spacemoose (Glen Stark) <https://github.com/spacemoose>`_. See also `#360 <https://github.com/fmtlib/fmt/issues/360>`_, `#335 <https://github.com/fmtlib/fmt/issues/335>`_ and `#331 <https://github.com/fmtlib/fmt/issues/331>`_.
+
+* Added ``container.h`` containing a ``BasicContainerWriter`` to write to containers like ``std::vector`` (`#450 <https://github.com/fmtlib/fmt/pull/450>`_). Thanks `@polyvertex (Jean-Charles Lefebvre) <https://github.com/polyvertex>`_.
+
+* Added ``fmt::join()`` function that takes a range and formats its elements separated by a given string (`#466 <https://github.com/fmtlib/fmt/pull/466>`_):
+
+  .. code:: c++
+
+    #include "fmt/format.h"
+ 
+    std::vector<double> v = {1.2, 3.4, 5.6};
+    // Prints "(+01.20, +03.40, +05.60)".
+    fmt::print("({:+06.2f})", fmt::join(v.begin(), v.end(), ", "));
+
+  Thanks `@olivier80 <https://github.com/olivier80>`_.
+
+* Added support for custom formatting specifications to simplify customization of built-in formatting (`#444 <https://github.com/fmtlib/fmt/pull/444>`_). Thanks `@polyvertex (Jean-Charles Lefebvre) <https://github.com/polyvertex>`_. See also `#439 <https://github.com/fmtlib/fmt/issues/439>`_.
+
+* Added ``fmt::format_system_error()`` for error code formatting (`#323 <https://github.com/fmtlib/fmt/issues/323>`_ and `#526 <https://github.com/fmtlib/fmt/pull/526>`_). Thanks `@maddinat0r (Alex Martin) <https://github.com/maddinat0r>`_.
+
+* Added thread-safe ``fmt::localtime()`` and ``fmt::gmtime()`` as replacement for the standard version to ``time.h`` (`#396 <https://github.com/fmtlib/fmt/pull/396>`_). Thanks `@codicodi <https://github.com/codicodi>`_.
+
+* Internal improvements to ``NamedArg`` and ``ArgLists`` (`#389 <https://github.com/fmtlib/fmt/pull/389>`_ and `#390 <https://github.com/fmtlib/fmt/pull/390>`_). Thanks `@chronoxor <https://github.com/chronoxor>`_.
+

+-----------------------------

+A custom ``format_arg`` function may be implemented and used to format any

+
+Note in the example above the ``format_arg`` function ignores the contents of

+
+   add_subdirectory(fmt)

+And then to ensure that the ``fmt`` library does not always get built, you can modify the call to ``add_subdirectory`` to read ::

+  ``double`` then the `~fmt::ArgVisitor::visit_double()` method of a subclass

+  then a corresponding method of `~fmt::BasicPrintfArgFormatter` or its
