| 1. need to add a test for the akima splines | |
| 2. [DOCUMENTATION] From: Conrad Curry <cwcurry@orca.st.usm.edu> | |
| I would suggest adding more about cspline and Akima similiar to what | |
| is given for 'polynomial', particularly under what conditions one | |
| would be prefered over the other. | |
| 3. add akima splines without the Wodicka modification, so that the spline | |
| is a smooth curve without corners. |
