Let's bring this class back, but without the confusing resize() API.
A FixedArray<T> is simply a fixed-size array of T.
The size is provided at run-time, unlike Array<T> where the size is
provided at compile-time.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
