Are there enough contexts for a plugin?

Some plugins can have a 'required contexts' item which can either be a context requirement object or an array of them. When contexts are required, items that do not have enough contexts should not appear. This tests an item to see if it has enough contexts to actually appear.

Parameters

$contexts: A keyed array of all available contexts.

$required: The required context object or array of objects.

Return value

bool True if there are enough contexts, otherwise False.
