• What is the current behavior?
  I want to be able to create a project for a customer. Inside a directory I want to create multiple SPGo instances for different site collections, e.g.:

• <Customer>/packages/<site_collection>/src

• <Customer>/packages/<site_collection>/SPGo.json

and

• <Customer>/packages/<site_collection 2>/src
• <Customer>/packages/<site_collection 2>/SPGo.json

In this example, SPGo will fail when run in the root dir <Customer>. It will only work, when VSCode was opened in the correct root folder, e.g. <Customer>/packages/<site_collection>.

• What is the expected behavior?
  When running any SPGo command that uses the file's context, i.e. Publish a major version of the current file, the extension should pick the closest SPGo.json file it can find.
