/**
 * Creates a predicate for type-checking object-shapes.
 *
 * For `true`, mandates that argument be of `typeof x === "object"`. For `null`, returns `false`
 *
 * @param properties The basic object shape. If an array - items from the array are treated as keys to be checked for presence on the passed `x`. Otherwise - an object, keys of which correspond to property names to be proven to be present, and to be passing of the predicates assigned to the respective keys. Defaults to `[]`
 * @param lacks The array of keys to be shown to definitively not be present on the object. Checked before `optional`. Defaults to `[]`
 * @param optional The array of properties to be allowed on the object in the event that `isStrict` is set to `true`. Defaults to `[]`
 * @param isStrict The flag for indicating whether the shape to be checked for is "strict", meaning - whether any properties other than `properties` and `optional` are allowed. Defaults to `false`

 *
 * interface IThing {
