Implemented as a REST API:
GET: http://servername/api/summaries

With the following options as query parameters:

crystalBall=true
Includes projected transactions for the current month and future months in the same time range as the original list of all transactions.

ignoreCcPayments=true
Used to ignore transactions from credit card payments in the calculations. When this option is used the output includes a list with all the pairs of transactions identifid as credit card payments. Credit card payment transactions are identified as having opposite amounts and created within 24 hours of each other.

ignoreDonuts=true
Used to ignore merchants that sell donuts (where the merchant is "Krispy Kreme Donuts" or "DUNKIN #336784"). Per design in the given instructions this list of ignored transactions is not displayed to the user. But a future improvement could easily show it, because the list is available just not displayed.

Output:
[
{
"ignoreDonuts": true|false,
"crystalBall": true|false,
"ignoreCcPayments": true|false,
"averageMonth": {},
"months": [],
"excludedCreditCardPayments": []
}
]
