+/**
+View class responsible for rendering the `<thead>` section of a table. Used as
+the default `headerView` for `Y.DataTable.Base` and `Y.DataTable` classes.
+
+Translates the provided array of column configuration objects into a rendered
+`<thead>` based on the data in those objects.
+
+
+The structure of the column data is expected to be a single array of objects,
+where each object corresponds to a `<th>`.  Those objects may contain a
+`children` property containing a similarly structured array to indicate the
+nested cells should be grouped under the parent column's colspan in a separate
+row of header cells. E.g.
+
+<pre><code>
+new Y.DataTable.HeaderView({
+  container: tableNode,
+  columns: [
+    { key: 'id' }, // no nesting
+    { key: 'name', children: [
+      { key: 'firstName', label: 'First' },
+      { key: 'lastName',  label: 'Last' } ] }
+  ]
+}).render();
+</code></pre>
+
+This would translate to the following visualization:
+
+<pre>
+---------------------
+|    |     name     |
+|    |---------------
+| id | First | Last |
+---------------------
+</pre>
+
+Supported properties of the column objects include:
+
+  * `label`     - The HTML content of the header cell.
+  * `key`       - If `label` is not specified, the `key` is used for content.
+  * `children`  - Array of columns to appear below this column in the next
+                  row.
+  * `headerTemplate` - Overrides the instance's `CELL_TEMPLATE` for cells in this
+    column only.
+  * `abbr`      - The content of the 'abbr' attribute of the `<th>`
+  * `title`     - The content of the 'title' attribute of the `<th>`
+  * `className` - Adds this string of CSS classes to the column header
+
+Through the life of instantiation and rendering, the column objects will have
+the following properties added to them:
+
+  * `id`       - (Defaulted by DataTable) The id to assign the rendered column
+  * `_colspan` - To supply the `<th>` attribute
+  * `_rowspan` - To supply the `<th>` attribute
+  * `_parent`  - (Added by DataTable) If the column is a child of another
+    column, this points to its parent column
+
+The column object is also used to provide values for {placeholder} tokens in the
+instance's `CELL_TEMPLATE`, so you can modify the template and include other
+column object properties to populate them.
