=head1 NAME

WWW::RiotGames::LeagueOfLegends - Perl wrapper around the Riot Games League of Legends API

=head1 SYNOPSIS

  use strict;
  use warnings;
  use aliased 'WWW::RiotGames::LeagueOfLegends' => 'LoL';

  my $lol = LoL->new( api_key => $api_key );
  # defaults ( region => 'na', timeout => 5 )

  my $champions = $lol->champions;
  my $champion_static_data = $lol->static_data( type => 'champions', id => 1 );
  my $summoner = $lol->summoner( summoner_name => 'Bob' );

=head1 DESCRIPTION

WWW::RiotGames::LeagueOfLegends is a simple Perl wrapper around the Riot Games League of Legends API.

It is as simple as creating a new WWW::RiotGames::LeagueOfLegends object and calling ->method
Each key/value pair becomes part of a query string, for example:

  $lol->static_data( type => 'champions', id => 1 );

results in the query string

  https://na1.api.riotgames.com/lol/static-data/v3/champions/1
  # api_key is added on
