added code to emit excel graph
added API endpoint for upload data to excel
feat(export/data): wip adds mocked data export
wired up saving exported as Excel data into AngularJS
wip(export): scaffolds the normalization of the data to send to the API for export
wip(export): scaffolding concrete export methods
wip(export): using alert instead of inform()
wip(export): first type of graph (lines) is sending normalized data to the backend
correct call to export graphs method
made sure that "x" column is only exported once and removed some logging
wip(export data): passing the graph object to the exporters (instead of raw data)
wip(export): sets the title of the graph and the label of the x axis
fix(export): the linesExport now uses axis labels and graph title (for spreadsheet and filename)
wip(activeProject): removes unused localStorage in ProjectOpenController and adds diagnosing debugger in a couple of places
wip(activeProject): introduces resetFor(user) and setProjectFor(projectName, user)
wip(activeProject): separates load from set active project; improves actions of the activeProject service; gives to the app a change to do things on logout that are actually under its responsibility
fix(activeProject): fixes ifActiveResetFor and cleans up debugger in diverse places
merged conflict + giving standard name to worksheet (due to 32 character restriction)
implemented missing types of export graphs (except pie graphs)
small code cleanup
