// Abstract:
// This module contains functions which prepares and sends data for the PEND_ENDPOINT_CLOSURE
// scenario implementation.
//
// Naming Convention:
//
// <Scope><Object><Action><Modifier>
//
// i.e.
//
// <Scope>
// {
// - Function is likely visible to other modules.
// Prv - Function is private to this module.
// }
// <Object>
// {
// PendEndpointClosureScenario - Function pertains to all of the Pend Endpoint Closure
// Scenarios.
// }
// <Action>
// {
// Execute - Function packages data and invokes RPC to the WFPSampler
// service.
// Log - Function writes to the console.
// Parse - Function pulls data into the required format from the
// provided data.
// }
// <Modifier>
// {
// ClosureData - Function acts on the PC_ENDPOINT_CLOSURE_DATA.
// Help - Function provides usage information.
// }
//
// Private Functions:
// PrvPendEndpointClosureScenarioParseClosureData(),
//
// Public Functions:
// PendEndpointClosureScenarioExecute(),
// PendEndpointClosureScenarioLogHelp(),
