Begin Node data structure
Moved everything to the main folder
Renamed backend.go to main.go
Refactor API and server architecture somewhat
Ignore nodeatlas binary
Add some simple logging and a Version number
Rename main.go to nodeatlas.go

This is to conform to previous standards.
Add DB architecture and sqlite3 support
Ignore sqlite3 databases
Add skeleton database structure and initialization

Running nodeatlas will now create a database (example.db by default)
with a single table, 'nodes,' which has a single column, 'addresses.'
viewing /api/status will query this database for the number of rows in
'nodes,' which will be zero.
