Merge pull request #397 from akshaydixi/LineScan/fitSpline

 #324 LineScan.fitSpline implemented. I am going to merge this in but be aware that there is no test, I am going to accept it because there is example code with output. We need to break out the line scan tests into a separate test suite. Once we get that up and running we will need a test for this.
standard got broken again, please don't remove these.
