Hello James,

I had make some tests with the average-mode and found two bugs. If you want, you should correct this two lines:
r.push((e[1]-e[0])); //error corrected was r.push(2*(e[1]-e[0])); !!!
r.push((e[i]-e[i-1])-((r[i-1]*h[i-1])/u[i-1])); // error corrected was r.push((e[i]-e[i-1])-(r[i-1]*h[i-1]/u[i-1]));!!!
in basicFunctions.js -splineMap-function.

Have a nice day
Karsten
