all_samples() in IJBC

Hi,

When trying to get all_samples() for ijbc dataset, I face with the following error:

>> from bob.bio.face.config.database.ijbc import database
>> database.all_samples()

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-11-9f954791c55f> in <module>
----> 1 database.all_samples()

AttributeError: 'IJBCDatabase' object has no attribute 'all_samples'
