+//Spiral Notes
+//-------------------------------------------------------------------
+//Height = center to center height of the end spheres which form the spirals.  Ends will need to be flattened by the user as desired.  Actual height of the rendering is Height+2*baseRadius
+//Radius = the maximum distance from the axis of the spiral (the z axis) to the center of the sphere(s) forming the spiral
+//baseRadius = cross sectional radius of the spiral
+//frequency = the number of complete revolutions about the axis made by the spiral, whole numbers will result in spirals whose tops end directly above their bases
+//resolution = integer number of spheres, not to be confused with $fn.  The greater the number of spheres, the smoother the spiral will be (also longer render times!).  Recommended that this number be 8*frequency or greater.
+//numSpirals = integer number of spirals used in the spiralMulti modules spaced evenly around the axis (3 spirals are spaced 120 degrees apart, 4 spirals: 90 degrees apart, etc.) 
+
+//Instructions
+//------------------------------------------------------------------
+//1. Place spiral.scad in the "libraries" folder of your openscad installation.  Find the libraries folder by File -> Show Library Folder...
+//2. Then create a new or open one of your existing scad files and include spiral.scad with the following code:  
+//use<spiral.scad>;
+//3. Then call the modules in your files with code similar to the following:
+//spiral(20,20,3,1,25);
+//spiralCone(20,20,3,1,25);
+//spiralEllipse(20,20,3,1,25);
+//spiralMulti(20,20,3,1,25,3);
+//spiralMultiCone(20,20,3,1,25,3);
+//spiralMultiEllipse(40,60,3,1,32,3);
