Checks if `predicate` returns truthy for **all** elements of `collection`.
The predicate is bound to `thisArg` and invoked with three arguments:
(value, index|key, collection).

If a property name is provided for `predicate` the created `_.property`
style callback returns the property value of the given element.

If a value is also provided for `thisArg` the created `_.matchesProperty`
style callback returns `true` for elements that have a matching property
value, else `false`.

If an object is provided for `predicate` the created `_.matches` style
callback returns `true` for elements that have the properties of the given
object, else `false`.

@category Collection
@param {Array|Object|string} collection The collection to iterate over.
@param {Function|Object|string} [predicate=_.identity] The function invoked
 per iteration.
@param {*} [thisArg] The `this` binding of `predicate`.
@returns {boolean} Returns `true` if all elements pass the predicate check,
 else `false`.
@example

_.every([true, 1, null, 'yes'], Boolean);
// => false

var users = [
  { 'user': 'barney', 'active': false },
  { 'user': 'fred',   'active': false }
];

// using the `_.matches` callback shorthand
_.every(users, { 'user': 'barney', 'active': false });
// => false

// using the `_.matchesProperty` callback shorthand
_.every(users, 'active', false);
// => true

// using the `_.property` callback shorthand
_.every(users, 'active');
// => false
