node dependencies, fleshed out index some more, added initialize
forgot to import init
better name for init
BaseMap class, initialize done, remembered package.json

Also updated test to try to draw on the page

A lot of scaffolding is up, just need to define some functions.
i think everyting (but axes) is in place for streamgraphs
got started with a Point class to handle generic data points. Not done yet, or
used
typos! also getting test to call the index.js

due to an error in statement of span, (or something) javascript was eating all
available memory, now fixed
