Use your own named 'keys' with meaning. (only letters, numbers and underscores)

There is a free token in these demos to mess with. The free token has restricted 
credential and response time of 4 seconds. There are 4 types of tokens accounts. 

    - 0 is the free token, and has ben generated for demo purpose. A token for account type 
        1 is generated on social logins. This token have a wide range of access for a decent 
        rig of devices. 
    - 1 social login, has the response time 1 second. Email relay is working with 
        Google social login token, because is the only social login which provie us with 
        your email. 
    - 2 paid token, with extended capabilities. 
    - 3 dedicated server, custom payloads
Once you have been authenticated either social login or PayPal you will have a token. 
The token is shown in the status bar. You dont have to stay logged in once you have the token.
Save it in a file so you can use it from anywhere, anytime. If you log in with different 
social logins you can have 3 different tokens, but there is no need, because
on a token you can have create many keys.
The number of active keys per token depends by the account you have. 
If you relog at later date with same social credentials the initial token would be handed back.
On each token you can have at any time 

    - Account 1 (social login)  maximum 16 keys and maximum 32 items in queue.    
    - Account 2 (19$)           maximum 64 keys and maximum 36000 items in queue. 
    - Account 3                 custom.
- A key which has not been updated for 2 days, except mail reminders is deleted.
- A queue push can overflow the queue if pop has not been called for long time. When
  the queue overflows, oldest value is deleted.
- Social login credentials can be deleted using the token generated with.

2018 June 4       https://meeiot/act/TOKEN          Activity report on token, last 400 entries.
    check the free token:

API's      stores a value under a key      get's a value from a key, updates last access time     push a value to the head of the key queue. (keep adding)      pops (removes) a value from the tail of the key queue. updates last access time      deletes the key / or a value for a key      Deletes the account associated to token. TOKEN remains active, but the account
                            and all user information associated with the TOKEN is deleted.
                                 all the keys and values for token         just the key and it's val                     deletes all the queue(s) or one queue           all the queues       just the queue  {HTTP_POST JSON}          {from: to: subject: message:}    sends an email/ or callback mail reminder    


Test User token: $TOKEN
    Operations using demo user id has a delay of 4 secoonds.
    Mail service is disabled for test token
    see the extra hdr="headers,..." attribute
    If HTTP_POST has the 'hdr' field  hdr="HTTP_HEADERS,COMMA,SEPARATED", then when the value
    id taken back, proper http headers are send before the value.
# This is a demo token and has restricted access. Many users can mess with.
