Nenue@6: Turok: Dinosaur HUD

Nenue@6: Hardcode of various WeakAura configurations. This is created as a personal learning challenge, so it may or may not be faster than the actual jumble of WeakAuras because that addon is written very well.

Nenue@6: Project Goals:
Nenue@6: 
Nenue@6:  - Focus bar with dynamic coloring and prediction lines based on talent effects
Nenue@6:  - Unit cast bars that are thematically linked with everything else
Nenue@6:  - Dynamically arranged tracking icons and sliders cooldown/aura information
Nenue@6:  - Quality-of-life alerts for Lone Wolf and Aspect of the Pack

Nenue@6: Coding Conventions:
Nenue@6: 
Nenue@6:  Although AceAddon modules are used, the addon is not truly modular.
Nenue@6:  The structure provides simple control over the internal loading sequence.
Nenue@6:  So if needed, "module" enables can be scattered over several post-load frames to make in-combat /reload less hazardous.
Nenue@6: 
Nenue@6:  SavedVars data is arranged in a non-propagating hierarchical metatable.
Nenue@6:  Accessing a deeply-nested member will traverse its parents until one of them contains data.
Nenue@6:  The only exception to this is on lazy read expressions, such as:
Nenue@6: 
Nenue@6:    > if (childtable.unsetvar) then
Nenue@6: 
Nenue@6:  This will always yield a false, whether or not a value is assigned in its parents.
Nenue@6:  To check for hierarchical flag variables, you can compare the index against nil, like so:
Nenue@6: 
Nenue@6:    > if (childtable.unsetvar ~= nil) then
Nenue@6: 
Nenue@6:  The operation will trigger __index and a value from the hierarchy will be presented.
Nenue@6:  Any positive flag state will be copied down when direct assignment is used.
Nenue@6:  To get a useful flag state, you need to run the first logical expression within a ternary idiom:
Nenue@6: 
Nenue@6:    > childflag = (childtable.unsetvar) and true or nil    -- pulls the true flag value
Nenue@6:    > parentflag = childtable.unsetvar                     -- pulls any non-nil value
Nenue@6: 
Nenue@6:  Another thing to note is hierarchical values are not assigned downstream.
Nenue@6:  If an empty child value is indexed, it will always traverse up the tree.
Nenue@6:  As a result, values consulted frequently will be computationally taxing.
Nenue@6:  These should be copied into a local variable and read from that instead.
Nenue@6:  Then, when an event that might change the value is detected, the local variable is updated instead.
Nenue@6:  From a performance standpoint, the effects are net-positive, since assignments potentially cover dozens of keys.
Nenue@6:  The memory footprint also isn't much different, while the assignment operations are carried out in spaced intervals.
