 Apply JSONPath expression _query_ to _value_. _value_ should arbitrary, possible nested, Python dictionaries, lists, strings, integers, floats, Booleans or `None`, as you would get from [`json.load()`](https://docs.python.org/3/library/json.html#json.load).

 `find(query, value)` is a convenience function for `JSONPathEnvironment().compile(query).apply(value)`. Use `compile(query)` to obtain a `JSONPathQuery` instance which can be applied to difference JSON-like values repeatedly.
