Scoped-Arena

Scoped-Arena provides arena-like allocator with optional scopes. Arena allocators are simple and provides ludicrously fast allocation.

Scope allows storing values. When dropped Scope will Drop all stored values and free memory allocated by the scope.\ Well placed scopes can significantly reduce memory consumption.\ Creating new scope is cheap and allocating within scope is as fast as allocating parent arena allocator.\ Drop glue is stored in scope only for values that needs_drop. i.e. for Copy types storing value on scope is simply allocation + copy.

Rust borrowing rules require additional layer of ScopeProxy to allow references to values on scope and sub-scopes to coexist.
