Sometimes you have to do horrible things, like use the global object to share a singleton. Abstract that away, with this!

This attaches a cache to the global object. It attempts to make it as undiscoverable as possible:
 - uses Symbols if available
 - if not, uses a string key that is not a valid identifier, so as not to show up in dot-notation browser autocomplete
 - makes it non-enumerable if property descriptors are supported

Keys are required to be strings or symbols.

## Example

```js
var cache = require('global-cache');
var assert = require('assert');

var value = {};
assert(cache.get(key) === undefined);
assert(cache.has(key) === false);

cache.set(key, value);
assert(cache.get(key) === value);
assert(cache.has(key) === true);

cache.delete(key);
assert(cache.get(key) === undefined);
assert(cache.has(key) === false);
```

## Tests
Simply clone the repo, `npm install`, and run `npm test`
