Query of Arbor Default collection is working.  Able to extract a tree in nested format and draw the custom d3 tree!  Node names or search by map are not working yet.
Phylotree interaction is working well.  Phylomap is non-functional yet.

Changed service for tree to phylotree.py; added branch-length and node names to the tree display.  Started to restore mapping function, which will be harder without mongo, since location searches were done in mongo, generally.  There is no concept of node IDs anymore, either.  Node IDs are assumed in the current clade selection and mapping algorithms.
Adding map markers.  Location markers work when clade selection is done on taxa nodes, but not on hierarchy nodes yet.  Had to build node lists to replicate searching we used to have in mongoDB.  This version may not scale as well because of client side computing requirements. It is beginning to  work, though!
