+
+Grids
+=====
+
+A "grid" in Tailbone is just a "displayed table" essentially, but may
+have other goodies connected with it, e.g. a set of filters and paging
+info.
+
+The main class is :class:`~tailbone:tailbone.grids.core.Grid` and most
+of the time you'll just use that, with no need to subclass it.
+
+Note that within a :class:`~tailbone:tailbone.views.master.MasterView`
+you can get a reference to the ``Grid`` class via
+:meth:`~tailbone:tailbone.views.master.MasterView.get_grid_factory()`.
+
+
+Types of Grids
+--------------
+
+The ``Grid`` class is used for a few different things, as described
+below.  Some of the features mentioned are described in the next
+section.
+
+Master CRUD w/ DB Table
+~~~~~~~~~~~~~~~~~~~~~~~
+
+By far the most common type is that used by the ``MasterView`` class,
+to expose a given data set for searching, downloading etc.  Usually
+the data set is just a DB table, so columns map directly between the
+table and grid.
+
+This grid usually allows user to specify filters and sorting/paging
+info.
+
+Master CRUD w/out DB Table
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Less common than the above, some ``MasterView`` classes need to expose
+a grid but the data set does not map to a DB table.  Examples of this
+are the Email Settings grid, and the Tables grid.
+
+This grid often does not allow filtering or paging, on account of the
+relative difficulty to implement (read: author is lazy), but often
+does allow basic sorting.
+
+Master "Rows" CRUD
+~~~~~~~~~~~~~~~~~~
+
+Similar to the above, this grid is used by ``MasterView`` to show
+"child row data" when viewing a particular object record.
+
+Like the first, this grid usually allows filter/sort/paging.  The one
+difference in this regard, is the user is not allowed to save default
+settings for the grid.  This is because (per current logic) each grid
+of this type is unique to the parent object, and settings are kept
+separate for each such grid.  So if settings were saved, they still
+would not apply to other grids.
+
+Field Data
+~~~~~~~~~~
+
+This type of grid is used to show a small-ish table of data, within a
+given form field, when viewing a particular object record.  For
+example when viewing a Role, this is how the Users field is displayed.
+
+This grid normally does not allow filters or paging, but in some cases
+may allow basic sorting.
+
+
+Grid Features
+-------------
+
+Here we discuss some possible features a grid may have.
+
+Columns
+~~~~~~~
+
+Obviously a grid has columns.  But a grid may also have some
+"invisible" columns, for sake of the data they contain.  This
+sometimes is needed for other automation etc. in the client-side UI.
+
+TODO: one of these days, grids should let user choose which, and in
+which order, columns are shown.
+
+Sorting
+~~~~~~~
+
+This is arguably the simplest enhancement to make to a grid.  Only a
+visible column may be sorted, but not all of them.  (It depends on the
+nature of the data set etc.)
+
+Paging
+~~~~~~
+
+With sorting comes the possibility of paging the grid data.  (Sorting
+is required for paging, so the results are deterministic.)
+
+Filters
+~~~~~~~
+
+Many grids allow the user to apply a set of filters, to limit which
+data is shown in the grid.
