Challenge Lab #2 (Assignment #21)

	    Adding a Random Keyed Humor button
    
   
	1)
	    I added this method to the humorHttp Interface:

	     getRandomKeyedHumor(type: string) : Observable<KeyedHumor>;


	2)
	    I added this implementation of the new method to the humor.service.ts file:


	    private randomKeyedHumorURL = "/keyed/random/";

	    getRandomKeyedHumor(type: string) : Observable<KeyedHumor> {
	          return this.http.get<KeyedHumor>(this.humorRestURL + this.randomKeyedHumorURL + "/" + type);
            }; 


	3)
	    I added this the bottom of keyed.component.html from:

	    <div class="float-start">
	            <button type="button" class="btn btn-primary" (click)="findRandomKeyed()">Find Random</button>
            </div>


	4)
	    I add the new method used in the HTML to the keyed.component.ts file

	    findRandomKeyed(): boolean {
	      this.humorService.getRandomKeyedHumor(this.category.id).subscribe(results => {
	        this.keyedHumor = results;
	        });  
	      return false;
           }
