Created branch. Converted the project to VS 2012 and rebuilt it.
Implemented plotting to file (Plot.h / Plot.cpp)
Plotting the actual data (plot.txt) from exB and
not the test data (test.txt)
Described the algorithm in the report for ex. b)
Added methods for calculating relative error in ex. c) + a method to get the analytic solution
Made print to file take a matrix as argument instead of 2 vectors.
Updated the test code for this method as well.
(TODO: Make the last element x = 1. Should still be n elements.)

What is a .suo file anyway? Whatever it is, VS must have changed it.
Merge pull request #1 from OPSand/vs2012

We both now use VS 2012, so a merge is safe.
