A Few Suggestions

[csaleman]

First thank you for for this API. Took me way too long to get the td_credentials.json file. So here is a list of issues I found.

1. The instructions don't show an example of the config.init file.
   [main]
   client_id = MY-OWN-CLIENT-ID
   redirect_uri = MY-REDIRECT-URI

2. The example fails to generate a credential.json in order to initiate the oauth workflow the line below needs to be omitted.

   credential_file='config/td_credentials.json'

3. URL was not showing, I'm developing on a VM without a web browser. So I added a print(url) on credentials.py right after line 468

   webbrowser.open(url=url)
   print(url)

4. After entering the code, nothing actually got saved, The token file was available but not saved. So I added the

td_credentials.to_credential_file('config/td_credentials.json')

# Initialize the Parser.
config = ConfigParser()

# Read the file.
config.read('config/config.ini')

# Get the specified credentials.
client_id = config.get('main', 'client_id')
redirect_uri = config.get('main', 'redirect_uri')

# Intialize our `Credentials` object.
td_credentials = TdCredentials(
    client_id=client_id,
    redirect_uri=redirect_uri
)

td_credentials.to_credential_file('config/td_credentials.json')
