<p>An <code>EntityList<T></code> type provides similar functionality to <code>Vec<T></code>, but with some important
differences in the implementation:</p>
<ol>
<li>Memory is allocated from a <code>ListPool<T></code> instead of the global heap.</li>
<li>The footprint of an entity list is 4 bytes, compared with the 24 bytes for <code>Vec<T></code>.</li>
<li>An entity list doesn't implement <code>Drop</code>, leaving it to the pool to manage memory.</li>
</ol>
<p>The list pool is intended to be used as a LIFO allocator. After building up a larger data
structure with many list references, the whole thing can be discarded quickly by clearing the
<p>The <code>EntityList</code> itself is designed to have the smallest possible footprint. This is important
because it is used inside very compact data structures like <code>InstructionData</code>. The list
contains only a 32-bit index into the pool's memory vector, pointing to the first element of
the list.</p>
<p>The pool is just a single <code>Vec<T></code> containing all of the allocated lists. Each list is
represented as three contiguous parts:</p>
<ol>
<li>The number of elements in the list.</li>
<li>The list elements.</li>
<li>Excess capacity elements.</li>
</ol>
<p>The total size of the three parts is always a power of two, and the excess capacity is always
as small as possible. This means that shrinking a list may cause the excess capacity to shrink
if a smaller power-of-two size becomes available.</p>
<p>Both growing and shrinking a list may cause it to be reallocated in the pool vector.</p>
<p>The index stored in an <code>EntityList</code> points to part 2, the list elements. The value 0 is
reserved for the empty list which isn't allocated in the vector.</p>
