General features

This is new package which provides single binary called mda_browser. This applications can be used to browser archived histograms. The GUI is based on the one of the OH Display and the way of interacting with it is quite straightforward. Just run it and browse the tree on the left side which consists from 4 main layers:
Each type of items has different icon so they can be easily distinguishable. For any item which is selected in the tree all available histograms appear in the right hand panel. Double clicking on a histogram will result in an attempt to display it. Here there are several possibilities which are automatically checked by the browser:
  1. If this histogram is available in the file which has already been downloaded from CASTOR then it will be immediately displayed
  2. Otherwise if the browser is running in ATCN (on a Point 1 machine) then it will try to get this histogram from the COCA cache directory
  3. If all of the above failed then a user will see a pop-up message asking whether he/she wants to download the necessary file from CASTOR. If the "Yes" button is pressed then download is started in the background and it's possible to continue browsing the archive content. As soon as download is finished the new ROOT Canvas window will be created with the requested histogram. In order to monitor the status of the CASTOR files download one can switch on the Download Monitor window by pressing the last button in the browser's tool bar.
