docs: Load an entity instance given the raw column slice. This is a stop gap
  solution for instanting objects using entity manager while iterating over
  rows.
  
  @param <T>      The type of entity to load for compile time type checking
  @param clazz    The type of entity to load for runtime instance creation
  @param id       ID of the instance to load
  @param colSlice Raw row slice as returned from Hector API, of the type
  <code>ColumnSlice<String, byte[]></code>
  @return Completely instantiated persisted object
