=head1 NAME
Locale::CLDR - A Module to create locale objects with localisation data from the CLDR
=head1 VERSION
Version 0.25.1
=head1 SYNOPSIS
This module provides a locale object you can use to localise your output.
The localisation data comes from the Unicode Common Locale Data Repository.
=head1 USAGE
 my $locale = Locale::CLDR->new('en_GB');
or
 my $locale = Locale::CLDR->new(language_id => 'en', territory_id => 'gb');
  
A full locale identifier is
  
C<language>_C<script>_C<territory>_C<variant>_u_C<extension name>_C<extension value>
  
 my $locale = Locale::CLDR->new('en_latn_GB_SCOUSE_u_nu_traditional');
  
or
  
 my $locale = Locale::CLDR->new(language_id => 'en', script_id => 'latn', territory_id => 'gb', variant => 'SCOUSE', extensions => { nu => 'traditional' } );

=head2 Territory Containment
=over 4
=item territory_contains()
This method returns a hash ref keyed on territory id. The value is an array ref
Each element of the array ref is a territory id of a territory immediately 
contained in the territory used as the key
=item territory_contained_by()

is the territory id of the immediately containing territory.
=back
=head2 Numbering Systems
=over 4
=item numbering_system()
This method returns a hash ref keyed on numbering system id which, for a given 
locale, can be got by calling the default_numbering_system() method. The values
of the hash are a two element hash ref the keys being C<type> and C<data>. If the
type is C<numeric> then the data is an array ref of characters. The position in the
array matches the numeric value of the character. If the type is C<algorithmic>
then data is the name of the algorithm used to display numbers in that format.

=head2 Number Formatting
=over 4
=item format_number($number, $format, $currency, $for_cash)
This method formats the number $number using the format $format. If the format contains
the currency symbol C<¤> then the currency symbol for the currency code in $currency
will be used. If $currency is undef() then the default currency code for the locale 
will be used. 
$for_cash is only used during currency formatting. If true then cash rounding
will be used otherwise financial rounding will be used. 
=item add_currency_symbol($format, $symbol)
This method returns the format with the currency symbol correctly inserted
=item parse_number_format($format, $currency, $currency_data, $for_cash)
This method parses a CLDR format string into a hash ref containing data used to 
format a number. If a currency is being formatted then $currency contains the
currency code, $currency_data is a hashref containing the currency rounding
information and $for_cash is a flag to signal cash or financial rounding. 
This should probably be a private function.
=item round($number, $increment, $decimal_digits)
This method returns $number rounded to the nearest $increment with $decimal_digits
digits after the decimal point
=item get_formatted_number($number, $format, $currency_data, $for_cash)
This method takes the $format produced by parse_number_format() and uses it to
parse $number. It returns a string containing the parsed number. If a currency
is being formatted then $currency_data is a hashref containing the currency 
rounding information and $for_cash is a flag to signal cash or financial rounding. 
=item get_digits()
This method returns an array containing the digits used by the locale, The order of the
array is the order of the digits. It the locale's numbering system is C<algorithmic> it
will return C<[0,1,2,3,4,5,6,7,8,9]>
=item default_numbering_system()
This method returns the numbering system id for the locale.
=back
=head2 Measurement Information
=over 4
=item measurement_system()
This method returns a hash ref keyed on territory, the value being the measurement system
id for the territory. If the territory you are interested in is not listed use the
territory_contained_by() method until you find an entry.
=item paper_size()
This method returns a hash ref keyed on territory, the value being the paper size used
in that territory. If the territory you are interested in is not listed use the
territory_contained_by() method until you find an entry.
=back
=head2 Likely Tags
=over 4
=item likely_subtags()
A full locale tag requires, as a minimum, a language, script and territory code. However for
some locales it is possible to infer the missing element if the other two are given, e.g.
given C<en_GB> you can infer the script will be latn. It is also possible to fill in the 
missing elements of a locale with sensible defaults given sufficient knowledge of the layout
of the CLDR data and usage patterns of locales around the world.
This function returns a hash ref keyed on partial locale id's with the value being the locale
id for the most likely language, script and territory code for the key.
=back
=head2 Currency Information
=over 4
=item currency_fractions()
This method returns a hash ref keyed on currency id. The value is a hash ref containing four keys.
The keys are
