Programming exercise
==========================
given the results of two straight line fits with errors
calculate uncertainty on the intersetion coordinates.
Illustrative plot on slide 3.

Implement solution which

--> generates data
    think about having correlated and uncorrelated examples
--> fits lines with errors
--> calculates uncertainty

Think about interpretation of the results.
Plot distributions, scatter plots and whatever other control plots
you find interesting for explaining the problem.
