The IonicVoluteAlpha01 had a glaring error in the formula, bvalue instead of the correct beta.
The default parameters now re-create the volute with the "historic" proportions. The two end tangents are not horizontal.
Added a parameter for the eyeRadius, the inner end of the spiral. Renamed bvalue to bRadius.
In the event that the eyeRadius exceeds the bRadius, the bRadius is "inner" rather than "outer."
Negative values for Whorls or eyeRadius are strange. May add absolute value to them.

Next to do are sliders, counter clockwise, and start angle.
