Changed descriptive comment
Deleted original function and currency check

The child pages won't be "current" because this function is only
checking top-level pages marked as current
Corrected descriptive comments
Added conditional show of child pages
Added current class to current child page

So that it wouldn't highlight all following pages
empty currentChild variable
Reset htmlChild, undo currentChild reset
