SYNOPSIS
    This module checks the validation of CNP (personal numeric code) of
    Romania's citizens and offers information about the person.

     use Business::RO::CNP;

     my $cnp = Business::RO::CNP->new(cnp => 1551029000000);
     #or:
     my $cnp = Business::RO::CNP->new(1551029000000);

     print $cnp->valid ? "The CNP is valid" : "The CNP is not valid";

     print $cnp->sex;
     print $cnp->sex_id;
     print $cnp->birthday;
     print $cnp->birthday->ymd;
     print $cnp->birthday->strftime('%d %m %y');
     print $cnp->birthday->set_locale('ro')->month_name;
     print $cnp->county;
     print $cnp->county_id;
     print $cnp->order_number;
     print $cnp->checksum;
     print $cnp->validator;
     print $cnp->cnp;

METHODS
  valid
    This method returns 1 if the CNP is valid or 0 otherwise.

  sex
    This method returns 'm' if the person is a male or 'f' if is a female.

    The method returns 'unknown' if the sex id of the person (the first
    digit in the CNP) is 9 (for non-romanian citizens).

  sex_id
    The method returns the first digit of the CNP. This digit is odd for men
    and even for women. It is 1 or 2 for those born between January 1 1900
    and December 31 1999, 3 or 4 for those born between January 1 1800 and
    December 31 1899, 5 or 6 for those born between January 1 2000 and
    December 31 2099 and 7 or 8 for foreign citizens resident in Romania.

    The sex id 9 is also reserved for foreign citizens.

  birthday
    This method returns a DateTime object that holds the birth day of the
    person so you can call any DateTime methods on it as exemplified in the
    SYNOPSIS.

  county
    This method returns the county where the person was born or where he
    received the CNP.

  county_id
    This method returns the county ID which is the pair of digits 8 and 9 in
    the CNP.

    Bucharest has the ID 40 but its sectors also have their own IDs.

  checksum
    This method returns the last digit in the CNP and represents a
    pre-calculated value based on the first 12 digits of the CNP.

  validator
    This method calculates the checksum from the first 12 digits of the CNP
    and it should be equal to the result of the checksum method in order to
    prove that the CNP is valid.

  cnp
    This method returns the CNP given as parameter to the object
    constructor.
