Automatically generate part of the README.md for Clause/Contract

[dselman]

It would be very useful for maintainability, consistency, and accuracy to automatically generate part of README.md.

It could include the following generated information:

• Required Cicero engine version
• Name and Description (from package.json)
• Request/response type model and samples
• Emit type model and samples
• Sample.txt

This should be combined with any text written by the user in README.md, perhaps using a template syntax. E.g.

{name}
{description}
Requires Cicero: {ciceroVersion}

This is my really great clause template that rules the world.

Samples
{samples}

Request Types
{requestTypes}

Reponse Types
{responseTypes}

Emitted Types
{emittedTypes}
