  \brief The QInfoMatchDelegate class matches based on a ProcessInfo structure.

  The QInfoMatchDelegate class matches based on a ProcessInfo record.  If an
  attribute is set in the ProcessInfo record, the value must match
  exactly.  The only exception are the environment variables, which
  only need to match exactly for environment values set in the ProcessInfo
  record
