generateEdits

Implements the Field Code Forest (FCF) algorithm of Garfinkel et al (1986) to 
derive all essentially new implicit edits from an editarray. The FCF is really
a single, highly unbalanced tree. This algorithm traverses the tree, pruning many 
unnecessary branches, uses <code>blocks</code> to divide and conquer, and 
optimizes traversing order. See Van der Loo (2012) for a description
of the algorithms.

Please note: active development has moved to packages 'validate'
and 'errorlocate'. Facilitates reading and manipulating (multivariate) data
restrictions (edit rules) on numerical and categorical data. Rules can be
defined with common R syntax and parsed to an internal (matrix-like format).
Rules can be manipulated with variable elimination and value substitution
methods, allowing for feasibility checks and more. Data can be tested against
the rules and erroneous fields can be found based on Fellegi and Holt's
generalized principle. Rules dependencies can be visualized with using the
'igraph' package.
