[TASK] Export of yearly cashflows

[Jderrill]

---

Issue Description

Is your feature request related to a problem? Please describe.
It is difficult to understand the year over year cashflows or perform a discounted cashflow analysis without a proper data dump of the cashflows throughout the project lifetime.

Describe the solution you'd like
The ability to output the data for each year and each individual cashflow to a CSV file. The option to view each as discounted or not discounted would be useful as well.

Describe alternatives you've considered
I've been using the debug print out to access the cashflows, but it is difficult to extract data from the console/log file.

Up.

@worseliz are you guys planning to work on this capability?

@alfoa what is remaining after what was done in #33 ? This allows detailed output of the cashflow analysis with period-reporting breakdowns based on using the <Output> node to request detailed outputs.
