Descriptive Statististics Example Added_Rahman_Shadman_NE24_Spring2015
I added an example of how to compare two sets of data through measures of center and spread and created methods which print out statements and create tables to illustrate this.

I'm not quite sure what your idea is here, but these aren't appropriate additions to the pandas codebase.

If you're just using pandas, you should write code in your own modules instead of modifying the pandas codebase itself.

If you'd like to improve the pandas documentation with new examples, that's great, but you should make additions to the [actual documentation](https://github.com/pydata/pandas/tree/master/doc) instead of the source code for the pandas library itself.
