title: Will a Google Apps Script Library be loaded multiple times if it is included more than once?
body: <p>I have a project where I use libraries to deal with DB models management.</p>
  
  <p>If I have a <strong>Customers_Library</strong> library for Customers-related functions which needs my main <strong>DB_Connection_Library</strong>, and then I load in the same project the <strong>Orders_Library</strong> which also uses the latter as a dependency...</p>
  
  <p>Is GAPS smart enough to know both 'child' libraries are loading the same 'parent' library? Or is it each loading an instance of it?</p>
  
  <p>Thank you!</p>
