How to run

Make sure you have golang installed.
Clone and cd into what we'll call $DIR
Run mongod --dbpath="./db". This will start your database.
The command above will ocupy your terminal unless you run it with --fork. So, to make it simpler, just open another terminal and cd onto $DIR
cd into $DIR/src/heroes.
Run go build. It will generate an executable file called heroes.
And you guessed it, run it with ./heroes.

How to test

Swagger is not yet implemented, so for now I recommend using an API tester such as Postman.

Url	Method	Description	Body	Response
`/hero`	GET	Gets all heroes	none	An array of heroes
`/hero`	POST	Creates a new hero	{"id" : int, "name": string}	The new hero
`/hero/{id}`	GET	Gets a hero indexed by id	none	An hero
`/hero/{id}`	DELETE	Deletes an hero	none	The deleted hero
`/hero/{id}`	PUT	Updates an hero's name	{"name": string}	The updated hero
