Phase 2 of patient identifier validation.

Implements the Verhoeff check digit algorithm as an identifier validator. The Verhoeff algorithm catches all single errors (i.e. 'a' instead of 'b') and all transposition errors (i.e. 'ab' instead of 'ba'). See

Wagner, Neal. "Verhoeff's Decimal Error Detection". The Laws of Cryptography with Java Code. p 54. San Antonio, TX: 2003. http://www.cs.utsa.edu/~wagner/lawsbookcolor/laws.pdf
