Generate a cell containing a single, dynamically-generated number, centered within the cell. We can't just use generate-content-cell for these cells, because the number doesn't exist until the point where the template is called. Generate-content-cell does have the @nodes attribute, but that expects a node list, not a scalar value. The (X)eLaTeX version of this template also uses \makebox rather than a tabular to reduce the amount of horizontal space generated (we can do this because numbers don't include line breaks), and omits the @style and @align attributes, as they're pretty much irrelevant (for now, at least).
TODO: Is it possible to refactor both templates so that there's less code duplication?
@columns: The number of columns the cell spans. [default 1]
@rows: The number of rows the cell spans. [default @lectures-per-week]
@number: The number to be output in the cell. [default 0]
(XeLaTeX) only
@column-format: A LaTeX tabular column specifiation for the cell. [default c|]
(X)HTML only
@colour: The display colour of the cell, which maps to a predefined CSS class. [default white]

<!--
Note when using pre-code in LaTeX to provide formatting: because of the tabular environment, use the declaration forms, not the macros.
Generate a cell containing general content of some sort. In (Xe)LaTeX, the cell content is embedded within a tabular environment, as it may contain embedded line breaks. (A \shortstack would also work, but the line spacing doesn't look as nice as it does with a tabular.)
@columns: The number of columns the cell spans. [default 1]
@rows: The number of rows the cell spans. [default @lectures-per-week]
@align: The alignment of the content within the cell. [default center]
@style: Styling information for the cell.
- For (Xe)LaTeX, a string containing styling /declarations/ (e.g., \bfseries, \sffamily). You can't use the macro forms (e.g., \textbf, \textsf), because of the embedded tabular environment.
- For (X)HTML, a string containing CSS styling information. Note: use @align for cell alignment and @colour for cell colouring.
@nodes: An optional list of XML document nodes that are processed to generate the cell content. [default: all sub-nodes of the current context node]
(XeLaTeX) only
@column-format: A LaTeX tabular column specifiation for the cell. [default c|]
(X)HTML only
@colour: The display colour of the cell, which maps to a predefined CSS class. [default white]
