+h- and r-adaptivity.
+
+A:
+* h-adaptivity gets worse with increasing p (not correct)
+* GH: choose nIter=1 ==> all solutions are incorrect
+* GH: choose nIter=20 ==> all solutions are correct
+* GH: nIter = 5 and Dirchlet bc at x=1.5 ==> aweful for p=20, 100
+  Integration of f(x) is not accurate enough. ==> better integration formula needed, see integral(...)
+  
+B:
+* h-adaptivity is correct
+
+C:
+* r-adaptivity
+  looks suspicious, but similar to Mandl
