This crate provides the [`FreeList`] type to allocate pages/frames of virtual/physical memory:

```rust

use free_list::{FreeList, PageLayout};

let mut free_list = FreeList::<16>::new();

unsafe {

    free_list.deallocate((0x1000..0x5000).try_into().unwrap()).unwrap();

}

assert_eq!(free_list.free_space(), 0x4000);

let layout = PageLayout::from_size(0x4000).unwrap();

assert_eq!(free_list.allocate(layout).unwrap(), (0x1000..0x5000).try_into().unwrap());

```
