TCheckBoxList displays a list of checkboxes on a Web page.
The layout of the checkbox list is specified via {@link setRepeatLayout RepeatLayout},
which can be either 'Table' (default) or 'Flow'.
A table layout uses HTML table cells to organize the checkboxes while
a flow layout uses line breaks to organize the checkboxes.
When the layout is using 'Table', {@link setCellPadding CellPadding} and
{@link setCellSpacing CellSpacing} can be used to adjust the cellpadding and
cellpadding of the table.
The number of columns used to display the checkboxes is specified via
{@link setRepeatColumns RepeatColumns} property, while the {@link setRepeatDirection RepeatDirection}
governs the order of the items being rendered.
The alignment of the text besides each checkbox can be specified via {@link setTextAlign TextAlign}.
