from Preliminary_Market_Assessment so the form is fully optional end
to end.
Surfaces Stage 0 sources-and-uses currency fields (Total_cost_of_project,
Member_equity_raised, Member_loans_raised, Member_preferred_shares_raised,
Bank_debt_raised, Grants_Donations_Raised, Other_sources_raised) starting
