These functions were temporarily ripped out of Shiny and moved to the htmltools package. We've discovered that it's safe to keep including them in shiny; as long as the functions in shiny and the functions in htmltools are identical, the user won't receive a conflict warning.

Use \code{singleton} to wrap contents (tag, text, HTML, or lists) that should
|
|
be included in the generated document only once, yet may appear in the
|
|
document-generating code more than once. Only the first appearance of the
|
|
content (in document order) will be used.
