UnmanagedMemory.jl

This package provides two basic helpers for dealing with unmanaged memory, for example structs and arrays coming from alien C code.

UnmanagedArray is a simple AbstractArray that wraps a pointer. It's element type must be concrete and isbitstype.

The @unmanaged macro helps one create something akin to a mutable struct, which is really just a pointer with getproperty and setproperty! overloads.

@unmanaged mutable struct A <: SuperType
    x::Int
    y::Bool
end

The fields must all be concrete isbitstypes, and the type itself cannot be generic. These are similar limitations to C.
