replacing HN collections itemViewClass from nodeitemview to humonnodeview; add necessary styling; move key field into top of hn.hbs
annotations + clean up: annotated hn.prevNode/nextNode; cleaned up unused funtions for hnv; remove left over comments in hn.hbs; add animations back to hnv
restyled hnv; moved margin-left to hnv level; removed box shadow from inputs; change key field from input to textarea (same as contentfield for now) amongst other changes
remove unfocus command from prev/nextNode; fix commit/commitAndContinue by selecting for .content-field.literal and adding .literal class to the literal content-fields
more styling changes (for node.active and its margins / border); switch to dc to use focusActiveNodeView which calls focusKeyfield and focusValField; add a placeholder contentfield for colletion items
add nodeIdx to hn; have hn.hbs cf keys bind to nodeIdx when no key is specified (very hacky, tightly coupled to contentfield right now)
redo dc.commitAndContinue to correctly insert the nextBlank humon node; fix bugs in dc.focusAcitveNodeView: was using but nodeKey can be the empty string, which is falsy
 odds and ends clean up
hn.hbs: switch to view.content.nodeParent.isHash instead of view.content.hasKey; completely refactor ContentField, now is abstract class; have keyfield < contentfield and valfield < contentfield. refactor dC.commitChanges into commitKey and commitVal
update nodeIdx to be a one way computed property
completely restructure humon_node to use blocky span; restyle; add ProxyField and IdxField to ContentField; update dC jquery selectors
add placeholder functionality for key and val fields
