title: Unity Configuration using multiple config files
body: <p>Is there a way to configure a container in multiple configuration files? </p>
  
  <p>For instance, I want to register types for a container in a web.config file located at the root and also register types for the same container (and others containers) in the web.config file of sub-folders. </p>
  
  <p>And also register other types for others containers in a company.config file in path C:\Company\Framework\Configs. </p>
  
  <p>When I try to do this I get a ConfigurationError stating that the entry for the container has already been added.</p>
  
  <p>EDIT: any suggestions here
