added new file for DataStore
Merge branch 'master' into DataStore
DataStore can add and remove datasets
added function to dump a snapshot of the datastore
getDataSet now returns an object whose one and only property has the dataset name
Trying to get app.js and Chart.js to work with the new DataStore object
removed log message
setData function in Chart.js now accepts DataStore objects or manually set arrays
Fixed test for data object in importDataSet
importDataSet in Chart.js is now displaying data
