#Generation of a single random number

This module offers functionality to validate, format and generate Danish phone numbers.
The validation can recognise telephone numbers is the following formats as Danish phone numbers.
White space characters are ignored.
In addition to validation the module offers generation of valid danish phone numbers. The purpose of using generated phone number is up to the user, but the original intent is generation of varied sets of test data.
If you want to use OOP please have a look at:
If you are using Data::FormValidator

The following subroutines are to be used in a procedural manner.
This subroutine takes a string and validated whether it is a Danish phone number.
Returns 1 (true) or 0 (false), depending on validity.
Returns a phonenumber rendered according to the template parameter or the default.
This subroutine takes a string representing a phone number template and generates the amount specified by second argument: amount. If no amount is specified only a single random phone number is returned.
The subroutine returns an array, no matter what amount is specified.
This is the actual generating method used by "generate".
It takes a single parameter, a string indicating the template for the formatting of the phone numbers to be generated.
It returns a single random number representing a Danish phone number formatted as outlined by the specified template.
This method is used internally to validate template parameters. Please refer to Perl's sprintf for documentation.

I have been working in Telco for a long time. So validation and formatting of telephone numbers is something I have seen at lot of. This module is an attempt to sort of consolidate the numerous different regular expression solutions I have seen scathered over large code bases.
