Remove the lodash dependency

Since this is a library, forcing the user to use lodash is a problem.

In here there is a direct import of the whole lodash library.

It should be either removed and functionality should be manually written,. Or, only required functions from lodash should be imported.

Hey, I’m currently bundling the lodash’s methods that the tree uses inside the UMD bundle (dist/angular2-tree-component.umd.js). This bundle should be loaded when using SystemJS. I believe it also hides the global _ variable.

I have solved the problem by calling lodash.js’s noConflict() in main.ts. The Global variable _ is then returned to underscore.js. Thanks!

platformBrowserDynamic().bootstrapModule(AppModule);
…
_.noConflict();
