Module:No interwiki access

--------------------------------------------------------------------------------
--  No interwiki access restricts a module's usage to Fandom Developers Wiki.
--  This module is called on internal and project modules that are developed
--  specifically for Fandom Developers Wiki and do not support interwiki usage.
--  These modules are not part of the [[Global Lua Modules|global repository]]
--  and probably should be listed on a project page.
--  
--  If an error is thrown at line 38, the caller module is not being used on
--  Fandom Developers Wiki. In essence, this module is the Lua equivalent of
--  the following HTTP CORS (Cross-Origin Resource Sharing) response header:
--  
--  {{#tag:pre|Access-Control-Allow-Origin: https://dev.fandom.com}}&#010;
--  
--  To use this module, add the following on your module:
--  
--  {{#tag:pre|require('Dev:No interwiki access')}}
--  
--  @script             NO_INTERWIKI_ACCESS
--  @release            beta
--  @author             [[User:DarthKitty|DarthKitty]]
--  @author             [[User:8nml|8nml]]
--  @usage
--      
--      local p = {}
--      require('Dev:No interwiki access')
--      p.noop = function() end
--      return p
--
