Plot capabilities

[cfraces]

Create plot() method in Economics class

• plot() to represent cashflow, cum cashflow and waterfall chart with revenue, various cost and profit overall

[dungnguyensarasota]

Dear @cfraces please review the code in feature-oop

[cfraces]

Forgot to run test. Regression on instantiation of Economics(**params) Make "present_value, profitability, irr, payout, dpi, cash, cash_cum, revenue, income, cost" the attributes of the Economic object (initialize with None values) API should look like:

econ = Economics() econ.calculate(**param) print(econ.npv) ... 457740.57

[cfraces]

Remove compute() method from plot(). Can apply plot() to econ after running calculation() Add proper error handling (try: except) in plot if attributes are empty Add validate() method to Economics() to test that project_length matches production_arr size (You can do this after vectorization)
