Description of Feature

Implements new ui in react components with typescript, with claimHandlers as classes that all inherit from abstract Handler class.

Some Notes:

• we ran into some issues with web3 library along the way
• encountered some confusion around the referencing of claim vs data properties of claim objects
• employed a convention of prefixing interface names with a capital I (to help distinguish them from capitalized component names, for example)
• tried to minimize the use of stateful components, and instead use stateless functional components (React.SFC) as much as possible. This should make it easier to transition to Redux
• created app/statementGenerators folder, on front-end, to generate one-line claim description statements for each claim type
• created app/utils folder to separate out utility functions from react components
• structured app/components folder with nested folders inside, to organize the functionality and relationships of react components
• fixed form-rendering bug (see issue #38 (closed)) by using functional programming pattern of currying, or creating functions that return functions that will take future arguments (that are not yet available)

Related Tasks

• #32 (closed) (phase out use of any type in TypeScript)

What's Next?

• #33 (implement Redux for state management)
