upload.go

// upload.go provides a simple example of uploading a GPX file to Strava
//
// usage:
//   > go get github.com/strava/go.strava
//   > cd $GOPATH/github.com/strava/go.strava/examples
//   > go run upload.go -token=access_token
//
//   You will need an access token with 'write' permissions. You'll
//   need to complete the oauth flow to get one of those.
//
//   Note this will upload a dummy file to your account, so make sure you delete.
