- Removes the existing elxir project
- Sets up the go module.
- Sets up goose to use for database migrations.
- Begins setup of some other basic things such as the logger and the http server.

+# Migrations 
+We are using goose to manage migrations. 
+
+### Migrate Up
+The server will run migrations and get you caught up. 
+
+Otherwise you can do: 
+ ```
+ goose sqlite3 ./ligmotes.db up -dir migrations 
+ ```
+ from the backend folder. 
+
+### Create New Migrations 
+From the backend folder 
+ ```
+ goose sqlite3 ./ligmotes.db create <migration name> sql -dir migrations 
+ ```
