+Worked up versions of the files in
+  toxi.geom
+  toxi.geom.mesh
+  toxi.geom.mesh2d
+  test 
+which are based on doubles.
+Needed this for my own puropses, as I am developing a CNC machine with 30 meter scale, and 0.01mm resolution.
+
+Tactic was to make a new double based class for each of the current toxicLib classes.   
+Appended D to the class name where it was just a word ie
+     SphereD  vs Sphere
+Where the current class defined dimensionality, put the D preceeding the dimensionality  ie 
+     VecD3D  vs Vec3D
+
+Some few of the existing classes have new double methods inserted as they were allready of mixed precisions.  
+These include
+    toxi.math.MathUtils    as only a double version of random  and EPSD for a double epsilon
+    STLReader  no double version is appropriate, as STL has only 32bit numbers
+    STLWriter  convert any incomming double classes to floats before writing.
+    Matrix     The existing 3 flavors are mixed mode, no changes made.
+    GMatrix    is mixed mode, no changes made.
+
+For those classes which have constructors from self-same classes, and which have constructors from more primitive types, included cross
+precision constructors, and a file in test for same.
+These classes are:
+  AABB         AABBD      
+  Circle       CircleD    
+  Quaternion   QuaternionD
+  Sphere       SphereD    
+  Vec2D        Vec3D      
+  Vec4D        VecD2D     
+  VecD3D       VecD4D
