Return type of searchGeneric

[GoogleCodeExporter]

currently, searchGeneric returns List and searchUniqueGeneric returns 
Object. This means it must be explicitly casted when used, for example:

//Note: this also causes a compiler warning for unsafe cast
List<User> = (List<User>) userDao.searchGeneric(search);

User user = (User) userDao.searchUniqueGeneric(search);

However, there is a language feature that will determine the return type at 
compile time based on context. This may save some trouble...

public <Q> List<Q> searchGeneric(Search search);
public <Q> Q searchUniqueGeneric(Search search);

This could simply be used as follows...

List<User> = userDao.searchGeneric(search);

User user = userDao.searchUniqueGeneric(search);

The actual resolution to this was to remove searchGeneric and 
searchUniqueGeneric 
altogether and change search() and searchUnique() to use the approach listed 
above.

I can see advantages to the old way of having search return a list or objects 
of the dao 
entity type, however the necessity of having a searchGeneric in addition to 
plain search 
was pretty confusing. So I think we're better off with this change.
