xyDataClass 0.1dev

2d data class for people to play around with data
and learn some Python, and not worry about details of numpy,
matplotlib, etc..

Defines a Python data class 'Xydat' that contains two 
numpy arrays of the same length, where one is dependent
variable (ydata) and the other is the independent variable (xdata).

Xydat objects store x- and y-data, basic statistics (mean, variance), 
and has methods for common functions such as scatter
plot, linear regression between the two variables.

Helper functions defined and used:
-regress2d: performs linear regression of y against x
-makePseudo2d: makes random data to put into object

===============

To do before 0.2dev
Integrate package with Git to streamline development/release
Fix axes for scat()
Add generic least squares fit using linear algebra
Add save capacity: object.save('name')
