Display model descriptions in swagger-ui.

override-getMockSignature.js

// This needs to be injected into swagger-ui's index.html file after 'swagger-ui.js' (where getMockSignature is defined) 
// but _before_ it is used to render parts of the page. A horrible dirty hack.

var _originalGetMockSignature = window.Model.prototype.getMockSignature;

window.Model.prototype.getMockSignature = function newModelGetMockSignature(modelsToIgnore) {
	var model = this;

	var signature = _originalGetMockSignature.apply(this, arguments);

	if (model.definition && model.definition.description)
		signature = "<span class=\"hacked-in-model-summary\">" + model.definition.description + "</span>\n" + signature;

	return signature;
};
