Grid Framework version 1.3.2 released

Version 1.3.2 of Grid Framework has been approved by the Asset Store Team. The biggest news is the  addition of new coordinate systems for hexagonal grids. You have cubic coordinates, rhombic coordinates and the old odd herringbone coordinates now. Even herringbone and barycentric coordinates will be added at some point in the future for the sake of completion, but they are no priority.

The documentation received a complete overhaul. Rather than two manually typed PDFs you now have one automatically generated Doxygen documentation in HTML format. Previously you accessed it by double-clicking the PDF in your project view, not you can just go to Unity's help menu and the documentation will open up in your browser.
The user manual and scripting API are now together again. The top- and sidebar of the HTML can be used to quickly find what you want. There is also a new section called Legacy Support that contains information on changed or dropped features and how to restore them or upgrade your code. The changelog has also been added to the manual, thanks to Markdown you now have both a nicely formatted HTMl and a well readable plain text file.

There are also two new examles. The first example constructs a SimCity-like terrain mesh from a plain text file containing the heights as integers and allows you raise and lower vertices by clicking them. Just set up your grid, insert your height file and click play.
The other example uses polar grids to simulate a rotary dial, as found on old telephones. Click a number and the dial will rotate that much, print a message and then rotate back. This example can be used for circular GUIs, menus, clocks or anything else that needs to rotate around angles.

There is also the usual bug-fixing, vertex matrix methods got cut and the NearestFace/BoxG methods of rectangular grids have changed somewhat. You can find the exact details in the Legacy Support section of the documentation. Here is the full changelog:

- Hex Grids: new coordinate systems, see the manual page about @ref hex_grid for more information.
- New HTML documentation generated with Doxygen replaces the old one.
- Fixed a bug in `Angle2Rotation` when the grid's rotation was not a multiple of 90°.
- _New example:_ generate a terrain mesh similar to old games like SimCity from a plain text file and have it align to a grid.
- _New example:_ a rotary phone dial that rotates depending on which number was clicked and reports that number back. A great template for disc-shaped GUIs.
Some existing methods have changed in this release, please consult the @ref legacy_support page of the user manual.
- Rect Grids: changed the way `NearestBoxG` works, now there is no offset anymore, it returns the actual grid coordinates of the box. Just add `0.5 * Vector.one` to the result in your old methods.
- Rect Grids: changed the way `NearestFaceG` works, just like above. Add `0.5 * Vector3.one - 0.5 * i` to the result in your old methods (where `i` is the index of the plane you used).
- Hex grids: Just like above, nearest vertices of hex grids return their true coordinates for whatever coordinate system you choose.
I am sorry for these changes so late , but I realize this differentiation made things more complicated in the end than they should have been. It's better to have one unified coordinate system instead. Read the @ref legacy_support to learn how to get the old behaviour back.
