Global alignment setting not working

```
I am attaching a simple program that attempts to use the
p.align="r"

option as described in the online tutorial:

http://code.google.com/p/prettytable/wiki/Tutorial
(under per-column settings)

However, it looks like the global setting is ignored.
I am using prettytable 0.7.2 installed via easy_install.

The output of the program is given below:

+---------------+------------------+--------------+-------------+
| default | floatFmt1 | floatFmt2 | gFmt |
+---------------+------------------+--------------+-------------+
| 123456789.123 | 123456789.123400 | 123456789.12 | 1.23457e+08 |

Start by reproducing the reported program with PrettyTable 0.7.2 and compare the documented p.align="r" behavior under the tutorial's per-column settings. Trace how global alignment is applied to the rendered table; done means the setting changes the output alignment as documented without breaking the shown formatting cases.
