Immediate appeal

This works intuitively well from the start. Some things to look into:

1. Expand tree by default
2. Highlight only cell content, not cell border
3. Print non-printable characters as eg. \x81
4. Show number of rows in faint behind table name , eg. \033[2m#{rows}\033[m
5. Show highlighted table after n (configurable) milliseconds (default 1000)
6. Reduce excessive border use (eg. right pane number of rows)
7. Add scrollbar to help (didn't realize there was much more initially)

Replace keyboard shortcuts as follows:

• Tab: Go to table
• Shift + Tab: Go to tree
• Cursor Right: Go to table (when in tree)
• Cursor Left: Go to tree (when on first column in table)
• Replace ones difficult to reach on non-US keyboards, eg. []{}
