Is this an ES6 Symbol value?

Example

var isSymbol = require('is-symbol');
assert(!isSymbol(function () {}));
assert(!isSymbol(null));
assert(!isSymbol(function* () { yield 42; return Infinity; });

assert(isSymbol(Symbol.iterator));
assert(isSymbol(Symbol('foo')));
assert(isSymbol(Symbol.for('foo')));
assert(isSymbol(Object(Symbol('foo'))));
