Issue description

I updated Composer to it's most recent version earlier (v1.10.1) and have been getting a deprecation warning ever since:

Deprecation Notice: Class PayPal\EBLBaseComponents\BillingPeriodDetailsType_Update located in ./vendor/paypal/merchant-sdk-php/lib/PayPal/EBLBaseComponents/BillingPeriodDetailsType_Update.php does not comply with psr-0 autoloading standard. It will not autoload anymore in Composer v2.0. in phar:///usr/local/bin/composer/src/Composer/Autoload/ClassMapGenerator.php:201

I've looked through the release notes on Composer and found that they added the deprecation warning in v1.10.0.

As it says that the class will no longer be autoloaded in v2 of Composer, I thought I should let you know :)

Hey @james-mckinnon !

You are absolutely right. We may have to create a new class and deprecate this class to make sure it is backward compatible. @victormln I see that in your PR you have renamed the class. I believe this may cause older integration to fail if we merge this and release, unless we do a major release with new version. Thoughts ?
