Togglable comment blocks

/*
    To comment and uncomment any code in here requires one to separately
    add/remove both the start and end tags for the block comment, which can be a
    bit annoying if you're toggling a block frequently, or if the start and end
    points are far apart (and you're using Notepad, or something).

/*
    This is code that is commented out. The second block-comment-start tag, 
    below, is ignored as part of the comment (but only if the language does *not* 
    support nested comments).
/**/

//*
    This is the same code as above, but no longer commented out. The only
    difference is the single slash before the opening tag, causing it to be 
    commented out and leaving the line below as a legal construction. Thus by 
    adding and removing that single slash, one can "toggle" a block of code in 
    the absence of editor support.
