Options and terms logic

[bobetbat]

Here is the common logic of how to display and use options and terms.
The data source for options and terms is in the Bid

• General terms are in the terms array, in the root of the bid
• Options are in the root of the bid but consist of items (should be displayed in options list) and terms (should be displayed in the options terms list)

Data source of term is giving us the following information:

• term - term Id
• impl - term contract address
• txPayload - ABI encoded params to send to contract

term name and description can be obtained from the facility metadata (by term Id).
Using the name and description it is possible to build a list of records. Each record should have a button that can be used to initialize a term.
Clicking on the button should lead to a transaction sending: target - impl contract, txPayload must be passed as parameter (specific contract interface is not implemented yet);
Data source for options is options.items from the root of the bid. Names and descriptions of options items can be obtained from the facility metadata (by item id).
