ck_generate_rkeys

This function allows to create random record keys from a uniform distribution. If no seed is
specified, a seed value is computed from the input data set to allow for reproducability depending
on the input data set.

Data from statistical agencies and other institutions often
need to be protected before they can be published. This package
can be used to perturb statistical tables in a consistent way. The
main idea is to add - at the micro data level - a record key for each
unit. Based on these keys, for any cell in a statistical table a
cell key is computed as a function on the record keys contributing to
a specific cell. Values that are added to the cell in order to perturb
it are derived from a lookup-table that maps values of cell keys to
specific perturbation values. The theoretical basis for the methods
implemented can be found in Thompson, Broadfoot and Elazar
(2013) <https://unece.org/fileadmin/DAM/stats/documents/ece/ces/ge.46/2013/Topic_1_ABS.pdf>
which was extended and enhanced by Giessing and Tent
(2019) <https://unece.org/fileadmin/DAM/stats/documents/ece/ces/ge.46/2019/mtg1/SDC2019_S2_Germany_Giessing_Tent_AD.pdf>.
