DESCRIPTION

28   ALGORITHM
29       1.  The whole number (without checksum) is taken modulo 97.
30
31       2.  The checksum is difference of the remainder from step 1 to 97.
32
33   METHODS
34       is_valid($number)
35           Returns true only if $number consists solely of numbers and the
36           last digit is a valid check digit according to the algorithm given
37           above.
38
39           Returns false otherwise,
40
41       complete($number)
42           The check digit for $number is computed and concatenated to the end
43           of $number.
44
45           Returns the complete number with check digit or '' if $number does
46           not consist solely of digits and spaces.
47
48       basenumber($number)
49           Returns the basenumber of $number if $number has a valid check
50           digit.
51
52           Return '' otherwise.
53
54       checkdigit($number)
55           Returns the checkdigits of $number if $number has a valid check
56           digit.
57
58           Return '' otherwise.
59
60   EXPORT
61       None by default.
