Dynamic Field Validation

Obtains a paginated list of customers from an api and validates the given data, printing the id and invalid fields based on provided validation data.

Customers are dynamic json objects with an id. They can be validated based on the type and length of each field and fields can be marked as required.

Pagiantion data allows the program to make subsequent calls to the api to aggregate the full list of customers.
