title: JHipster deleting project
body: <p>I am looking for deleting a full Jhipster project (Cause their system to update entities is terrible, and their system to delete entities is ... non-existant.</p>
  
  <p>Anyway, I would like to go back from 0. Is deleting my project directory enough ? </p>
  
  <p>Won't it makes problems if I <code>yo generator-jhipster</code> on another directory after deleting my project's directory ?</p>
