'NotePad' under 'Lab Notebook' opens the activity that will be used for downloading and opening pdfs from a remote server. The icons will change eventually, but since NotePad was already there, I used that for initial code. Inside that activity there's a button that says 'Download Files' that opens a popup asking for the URL and path of the directory. The activity goes out and gets a list of files from that directory on the remote machine (Indexing must be enabling by the web server on the remote machine). The activity shows a multi-select interface where the user can choose which files or folders to download. Checking the boxes and hitting 'Download' doesn't actually do anything right now.
