Following Changes have been made:
1. conn -> CONN
2. CONN is now a global as a lot of functions were requiring it and
passing them as a parameter didn't seem intuitive.
3. In progressBar.go now we are sending only the short path instead of
absolute path.
- Added A new Struct Application which has all the other components as
its fields
-- the `newApplication()` Function returns a pointer to the newly
created Application from which other fields can be accessed. The
fields are as follows
| App *tview.Application
| expandedView *tview.Table
| Navbar *tview.Table
| searchBar *tview.Table
| pBar *progressBar
- Minor changes to main.go
