title: Initialise model object from table name
body: <p>Is there a way to instantiate a namespaced model object from its table name?</p>
  
  <p>eg: Given table <code>school_students</code>, model <code>School::Student</code>, id <code>30</code>, I could do:</p>
  
  <p><code>student = get_from_table_name_and_id("school_students", 38)</code></p>
