- added a select element and populated with alphabetized list of vertebrate names...doesn't control anything yet
- made the footer a header and separated from the tree div w/absolute positioning to avoid overlap else sometimes the nodes weren't clickable if they overlapped the tree
- made some changes to the update function to make it more apparent that the parent node positioning is getting used
- changed link.enter() and link.exit() to use the source property, since the links don't have a parent property
- fixed some JSON vertebrate names that had leading whitespace...found during alphabetizing
added unique 'id' key value to every vertebrate object
change select option value to the new unique id
hooked up the selector...was a little hairier than I thought, due to the parent lookups to expand them as well.
remove xtra console.log statement
move g_node below update, isn't shown in svg otherwise
add bug for presentation purposes, make links always enter/exit to and from the root node instead of parent
fix link bug not coming from parent node
