Fleshed out:
  features/trytond/account_stock_anglo_saxon/scenario_account_stock_anglo_saxon.feature

Added:
  features/trytond/account/scenario_account_reconciliation.feature
which now runs and passes. It still needs parameterizing with tables.

Added:
  features/trytond/product_cost_fifo/scenario_product_cost_fifo_stock_anglo_saxon.feature
which FAILS as it should for now because it is a copy of
  features/trytond/account_stock_anglo_saxon/scenario_account_stock_anglo_saxon.feature
changed to use FIFO, but the accounting results have not yet been updated.

Added:
   rst_to_feature.el
