Added Analytics API Sample

I added Analytics API sample on github. The sample is calling management.accounts.list API.

https://github.com/comewalk/google-api-perl-client/blob/master/eg/analytics/cli_private_access.pl

You can try the sample like below.

 # Edit Client ID and Client Secret
 $ vim eg/analytics/cli_private_access.pl
 $ perl -I lib eg/analytics/cli_private_access.pl

Also, I updated sample wiki page.

Oops, I forgot to mention changes.

• Implemented nested resource.
  For example, Analytics API Discovery Resource Document has nested resource section like below.

   "resources": {
    "management": {
     "resources": {
      "accounts": {
       "methods": {
        "list": {
  

  Then this module supported nested resource for now :)

Thanks!
