cache.set('a', 1);
cache.set('b', 2);

  [ { key: 'a', value: 1 },
    { key: 'b', value: 2 },
    { key: 'c', value: 3 } ]
*/
cache.get('c') //returns 3 and makes it most recently used
/*
[ { key: 'c', value: 3 },
[ { key: 'a', value: 1 },
  { key: 'b', value: 2 } ]
*/
cache.peek('a') //returns 1 but doesnt resets the order
/*
[ { key: 'c', value: 3 },
  { key: 'a', value: 1 },
