sq.texttable
~~~~~~~~~~~~

Creates simple ASCII tables
Based on texttables by Gerome Fournier
..'https://pypi.python.org/pypi/texttable/0.8.1'_

TextTable features not yet implemented:
1. Horizontal Alignment within cell (left, center, right).
   Currently set to left.
2. Vertical Alignment within cell (top, middle, bottom).
   Currently set to top.
3. Set column width.
   Currently set to auto.
4. Set precision on floats & exponential values
5. Values must be strings
6. Borders are a place holder for future development, not currently implemented
