Title: Collapsing Code Block

This pull request implements the collapsing code block.
To make the code collapsible, give a value for `collapse` in the options for `makeSagecell`. A value of `true` means that the code is collapsed by default; `false` means that it is not, but it is collapsible. If no option (or `undefined`) is given, the code block will not be collapsible.
