Expand description
It’s useful to be able to model an integral type such as u32 as being a series of bits,
instead of a whole number. There are, of course, the usual bitwise operators for simple stuff,
but the Bitmap trait provides more complex, specific operations that are useful for bitmaps.
A common use of the Bitmap trait is for memory allocators to track an area of pages, where
each bit represents a page. You might, for example, want to find a series of n zeros (which
would mark an area of n pages that are free to allocate) - the alloc method provides this
functionality.

Bitmap, but for arrays. This is unfortunately needed due to conflicting implementations.
