Replace the bob_bio_database to our nice Global Configuration System

Hi,

Since we have this very elegant way to define system global parameters in bob.extension (https://www.idiap.ch/software/bob/docs/bob/bob.extension/stable/rc.html), I think it's time to use this solution instead of bob_bio_databases.txt https://www.idiap.ch/software/bob/docs/bob/bob.bio.base/stable/installation.html?highlight=bob_bio_databases#databases

Basically we would replace this:

atnt_directory = "[YOUR_ATNT_DIRECTORY]"
database = AtntBioDatabase(
    original_directory=atnt_directory,
    original_extension=".pgm",
)

to this

from bob.extension import rc
database = AtntBioDatabase(
    original_directory=rc['bob.db.atnt.directory'],
    original_extension=".pgm",
)

We would need to update the following packages:

• bob.bio.base
• bob.bio.face
• bob.bio.vein
• bob.bio.spear

What do you think?

Cheers
