GetType will extract the type at the given path from the data Go struct E.g data = { Friends: []Friend{ { Name: "John" } }, path = "Friends.0.Name" will return "John".

GetValue will extract the value at the given path from the data Go struct E.g data = { Friends: []Friend{ { Name: "John" } }, path = "Friends.0.Name" will return "John".

IsNil test if a given value is nil.

ListFields will recursively list all fields path that can be used with GetType or GetValue.

ListFieldsWithFilter is the same as ListFields but accept a filter method that will be call for each fields.
