Test of integration using PyOpenCL.

First is a simple reduce to compute one simple integral. Then there is a
kernel performing integration on the interval [0,10] using 1000 points
on the function (x**2 - 10*x - i) where i is the index in the "resulting
vector" taking the value of every integer on the interval [0,1000000].
As of now this code finishes in under one second on my GPU...
Included comments of the code.
Made matrix generation through integrals work.

gen_matrix.py describes matrix generation through integration on a GPU.
The current integral is a very easy one..
Added a longer description of the file.
Matrix generation now almost works with our potential.

Calculates a 1000x1000 matrix in under two seconds, but converges a
little of the desired result... The code is currently a mess, I will
refactor it later this week.
Refactored and refined the PyOpenCL-implementation.
Same as the PyOpenCL-directory, but with double precission.
Now calculating and printing results
Removed copies
Ignored test-directory
fixed some functionality
started on complex contour
