+/**
+ * @author jonobr1 / http://jonobr1.com
+ *
+ * Creates a one-sided polygonal geometry from a path shape. Similar to 
+ * ExtrudeGeometry.
+ *
+ * parameters = {
+ *
+ *  size: <float>, // size of the text
+ *  height: <float>, // thickness to extrude text
+ *  curveSegments: <int>, // number of points on the curves
+ *  steps: <int>, // number of points for z-side extrusions / used for subdividing segements of extrude spline too
+ *  amount: <int>, // Amount
+ *
+ *  bevelEnabled: <bool>, // turn on bevel
+ *  bevelThickness: <float>, // how deep into text bevel goes
+ *  bevelSize: <float>, // how far from text outline is bevel
+ *  bevelSegments: <int>, // number of bevel layers
+ *
+ *  extrudePath: <THREE.CurvePath> // 3d spline path to extrude shape along. (creates Frames if .frames aren't defined)
+ *  frames: <THREE.TubeGeometry.FrenetFrames> // containing arrays of tangents, normals, binormals
+ *
+ *  material: <int> // material index for front and back faces
+ *  extrudeMaterial: <int> // material index for extrusion and beveled faces
+ *  uvGenerator: <Object> // object that provides UV generator functions
+ *
+ * }
