RiskModule
This contract allows risk partners and customers to interact with the protocol. It keeps the configuration of a single insurance product and is responsible for injecting policies and policy resolution.
The pricing responsibility — including validating and pricing new policies, replacements and cancellations — is delegated to an Underwriter contract plugged into the RiskModule. To create a new policy, the RiskModule is called with the raw input; it forwards it to the underwriter, builds the Policy object with the resulting fields, and submits it to the PolicyPool.

External Methods
newPolicy
function newPolicy(bytes calldata inputData, address onBehalfOf) public returns (Policy.PolicyData memory policy)
Creates a new policy. The premium is paid by msg.sender and the policy is owned by onBehalfOf.

|---|---|---|
| inputData | bytes | Input data decoded and priced by the underwriter to build the policy. |
| onBehalfOf | address | The address that will be the owner of the created policy. |
newPolicies
function newPolicies(bytes[] calldata inputData, address onBehalfOf) external
Creates several policies in a single call. The premium is paid by msg.sender and all the policies are owned by onBehalfOf.
replacePolicy
function replacePolicy(bytes calldata inputData) external returns (Policy.PolicyData memory policy)
Replaces an existing policy with a new one, with the same owner. The underwriter decodes both the old policy and the parameters for the new policy.
cancelPolicy
function cancelPolicy(bytes calldata inputData) external
Cancels a policy, giving back all (or part) of the pure premium and the non-accrued cost of capital.
resolvePolicy

| policy | Policy.PolicyData | The policy previously created (from the NewPolicy event). |

Returns the minimum premium computed by the Policy library for the given policy parameters.
