set up database

[amy-lei]

Set up our database using SQLite with a contacts table. Contact schema is as follows:

• id (or google id depending on choice of auth): string,
• name: string
• date_met: date object,
• location: string,
• email: string,
• links: array
• notes: array (or should we have a Note object?)

@amy-lei @ebonnecab we're also going to need a variable/key for notes; the main point of keeping track of these people is to remember what you learned from meeting them. comments: string
