-Z Function Surface
-
-This script lets the user create a surface where the z coordinate
-is a function of the x and y coordinates.
-
-    z = f(x,y)
-
-X,Y,Z Function Surface
-
-This script lets the user create a surface where the x, y and z
-coordinates are defiend by a function.
-
-    x = f(u,v)
-    y = f(u,v)
-    z = f(u,v)
-
-Usage:
-You have to activated the script in the "Add-Ons" tab (user preferences).
-The functionality can then be accessed via the
-"Add Mesh" -> "Z Function Surface"
-and
-"Add Mesh" -> "X,Y,Z Function Surface"
-menu.
-
-Version history:
-v0.3.6 - Various updates to match current Blender API.
-    Removed recall functionality.
-    Better code for align_matrix
-    Hopefully fixed bug where uMax was never reached. May cause other stuff.
-v0.3.5 - createFaces can now "Flip" faces and create fan/star like faces.
-v0.3.4 - Updated store_recall_properties, apply_object_align
-    and create_mesh_object.
-    Changed how recall data is stored.
-v0.3.3 - API change Mathutils -> mathutils (r557)
-v0.3.2 - Various fixes&streamlining by ideasman42/Campbell Barton.
-    r544 Compile expressions for faster execution
-    r544 Use operator reports for errors too
-    r544 Avoid type checks by converting to a float, errors
-    converting to a float are reported too.
-    Fixed an error Campbell overlooked (appending tuples to an
-    array, not single values) Thamnks for the report wild_doogy.
-    Added 'description' field, updated 'wiki_url'.
-    Made the script PEP8 compatible again.
-v0.3.1 - Use hidden "edit" property for "recall" operator.
-    Bugfix: Z Function was mixing up div_x and div_y
-v0.3 - X,Y,Z Function Surface (by Ed Mackey & tuga3d).
-    Renamed old function to "Z Function Surface".
-    Align the geometry to the view if the user preference says so.
-    Store recall properties in newly created object.
-v0.2.3 - Use bl_info for Add-On information.
-v0.2.2 - Fixed Add-On registration text.
-v0.2.1 - Fixed some new API stuff.
-    Mainly we now have the register/unregister functions.
-    Also the new() function for objects now accepts a mesh object.
-    Changed the script so it can be managed from the "Add-Ons" tab
-    in the user preferences.
-    Added dummy "PLUGIN" icon.
-    Corrected FSF address.
-    Clean up of tooltips.
-v0.2 - Added security check for eval() function
-    Check return value of eval() for complex numbers.
-v0.1.1 - Use 'CANCELLED' return value when failing.
-    Updated web links.
-v0.1 - Initial revision.
