Please tag 0.2.1

The following code causes a bug where the minimum is not enforced if the value is 0.

php-json-schema/src/Json/Validator.php

Line 422 in 62b2bb9

if (isset($schema->minimum) && $schema->minimum) {

It has been fixed in a later commit but the latest version composer can use is 0.2.0. Please tag a 0.2.1 on master.
