Wolfram Language: Create a daily map from Bouncie API webhook data

bouncie.wl

(*
Requires creation of a webhook on https://bouncie.dev to post to an Apache CouchDB database exposed to the Internet.
Substitute '6984' as the port number if you prefer a secure connection after setting up SSL according to the Apache
CouchDB Instructions.

The 'tripData' view used here to retrieve just tripData entries is as follows in CouchDB:

function (doc) {
  if (doc.eventType == 'tripData')
  emit(doc.data, null);
}

The variables 'Yesterday' and 'Today' are built into the Wolfram Language and do not need to be defined elsewhere;
but to avoid an error with conflicting date/time granularities, the 'Instant' option *must* be specified.
