Since ns-module-factory-loader contains dynamic require call, when it is webpacked, a context module is generated for it. By default, when a module is dynamically required by a context module it must reside in the same directory as the context module in order to be resolved by the webpack's require. This means that after this change in the sdk examples, the example app will crash with Module not found when a module that is not in the same directory as ns-module-factory-loader.ts is required.
This commit makes ns-module-factory-loader "webpackable" and "snapshotable" by replacing the call to the webpack require function (webpack replaces all require(..) calls to __webpack_require(..) calls) to call to the runtime's require function.
