Content contians the basic javascript functions to hide and unhide content and
highlight menu options. It requires a hiden field on the HTML page to hold which
menu item is currently being displayed. This hidden field is called 'booleanVar'.
Though it is not a boolean variable anymore.

//class='text' is the CSS class that controls the div tag (optional)
//id = the id of the header tag (this is used for mouseover, mouseout and onclick
//on a mouse over, it uses the change() function to change the look of the title,
on a mouse out, it uses the chnageBack() function to revert back to normal.
on a mouse click, we want to hide the orignal exposed content and open the content for
the title clicked on (this is done with the function hide(). We then want to change
the item back since the mouse really don't leave it, and then we want to scroll to
either the current title or the top title (the top title is less confusing, a user can
that their orignal titles did not dissapear)
//also note that the first item is not hidden (set: style="DISPLAY: Block") and all others
are (set: style="DISPLAY: none")
a sample of how this is used (place this in the html code):
content text here
