modifier

Create or read a set of data modification rules

Data cleaning scripts typically contain a lot of 'if this change that'
type of statements. Such statements are typically condensed expert knowledge.
With this package, such 'data modifying rules' are taken out of the code and
become in stead parameters to the work flow. This allows one to maintain, document,
and reason about data modification rules as separate entities.
