Get a value from memory given a path, returning None if any thing along the way does not exist.

Examples

Get a reference with type u32 at the path creeps.John.count.

#[macro_use]
extern crate screeps;

let mem = screeps::memory::root();
let val = mem_get!(mem.creeps.John.count.i32);

Get something using a variable path.

#[macro_use]
extern crate screeps;

let mem = screeps::memory::root();
let creep_name = "John";
let what_to_get = "count";
let val1 = mem_get!(mem.creeps[creep_name][what_to_get].i32);
let val2 = mem_get!(mem.creeps[creep_name].count.i32);
assert_eq!(val1, val2);

Accepted suffixes for type are methods that exist on MemoryReference, such as num, int, string, bool, arr and dict.
