[ENSCORESW-563]. Adding array and hash based content detection methods for regulation.

Nathan requested methods which can perform this kind of task (assert the contents
of a data structure). We support 1 level of arrays and hashes. All test cases
pass at time of writing. Methods for capturing method returns were
not implemented. They do not fit into the Utils way of doing (no method
actually performs a task on an object they just report what it is).
