File Information Display, added to DisplayArchive activity;

Split-screen display:
- Left   --> files in archive folder
- Right --> information regarding the file selected

Need to =>
- keep file selected while it's information is being displayed;
- control visibility of open select file button;
- add delete button functionality;
- display file/data type/kind
- add radar parameter settings used when the data was collected
- Other options:
  --> date last opened
  --> last modified
  --> GPS location of data, etc.

In MainActivity:
- add Save and Collect/Save button functionality
- regular Collect button will save a "temporary" file until it is
actually saved to memory
- save button should allow user to specify which data they want to save
- DISPLAY FILE NAME THAT IS OPENED!!

NewFile.java should...
- contain information specific to the instance of the file created:
--> Kind of data
--> radar parameters
--> date created
