Support capital gains income (1099 B), Schedule D

[zakpatterson]

Should be able to add data from multiple 1099 B forms, pdf output should include schedule D and accumulate to field number 64 on the 1040.

Todos:

• [x] Schedule D or Capital Gains and Qualified Dividends worksheet
• [x] Schedule D
• [x] Lines on 1040 (3a, 7)

Dealing with uncovered and unreported transactions is a separate issue:

• [ ] Schedule 8949 - used when basis is not reported to IRS, or for capital gains that are not reported on 1099B.
  • There are a number of types of transactions to report here:
    • (B) Short-term basis unreported transactions - required
    • (C) Short-term transactions not reported on form 1099-B - required
    • (E) Long-term basis unreported transactions - required
    • (F) Long-term transactions not reported on form 1099-B - required
  • User should be able to add list of transactions for B, C, E, F (note we should determine long term / short term)

@zakpatterson I think before capital gains and interest income are added the tax calculation 1040 fields 1-38 should be filled with default values or calculated so that the tax calculator gets to a very minimum viable product where someone could file their taxes on it if they fit a specific profile
