declared: Functions to Declare Missing Values

A set of functions to declare labels and missing values, coupled with associated functions to create (weighted) tables of frequencies and various other summary measures. Various base functions are rewritten to make use of the specific information about the missing values, most importantly to distinguish between empty and declared missing values. Many functions have a similar functionality with the corresponding functions from packages "haven" and "labelled". A lot of effort was spent to ensure as much compatibility as possible with these packages, with the intention to offer a complementary alternative for the objects of class "declared".
