Gets the static and dynamic dependencies for a class or group of classes.
| public static dependencies ( mixed $classes, array $options = [] ) : array | ||
| $classes | mixed | Either a string specifying a class, or a numerically indexed array of classes |
| $options | array | Option consists of: - `'type'`: The type of dependency to check: `static` for static dependencies, `dynamic`for dynamic dependencies or `null` for both merged in the same array. Defaults to `null`. |
| return | array | An array of the static and dynamic class dependencies or each if `type` is defined in $options. |

* @param string $dependency The class name to use as a dependency.
* @param string $exclude Regex path exclusion filter.
