Local templates

Angular provides a way to bind templates to a structural directive to organize the template code in a better way. For example this is implemented in the *ngIf structural directive under the else template slot. *ngIf="show; else: templateName".

This can reduce expressions in the template and save us boiler plate.

<div *ngIf="isTrue; else:elseTpl">Visible if true</div>
<ng-template #elseTpl>Visible if false</ng-template>

With directive's we can now provide custom template slots for any behavior.
