Python-based configuration system (closes #43)

This push provides a basic configuration system for Bob, python-based.

@andre.anjos two things:

1- the tests are failing.

2- After a lot of work with these configurations, I have always wanted to merge several configs into one bigger config. Let me explain: I would like to have a couple of configurations like this:

$ cat config_replay.py
database = 'replay'

$ cat config_replaymobile.py
database = 'replay-mobile'

$ cat config_databases.py
database.original_extension = '.hdf5'

And then the following commands:

$ command_line config_replay.py config_databases.py
$ command_line config_replaymobile.py config_databases.py

I know with jgen I can make the database variable a template and generate two configurations but I think having the ability to share variables between config files is far more powerful and allows for more modular creation of config files.

Here is another example:

# config_algorithm.py
algorithm = 'isv'
sub_directory = 'isv'

# config_database1.py
database = 'atnt'

# config_database2.py
database = 'mobio'
sub_directory += '-male'

Then I would have:

$ verify.py config_algorithm.py config_database1.py
$ verify.py config_algorithm.py config_database2.py

Is this possible/implemented?

@amohammadi: with the latest commits, the way you want to use the config system will work out of the box. Read the docs for explanations.

Builds are now green. There are 25 lines of code implementing the whole functionality.

I wonder this model of configrc can be used for environment variables as well. Like BOB_DOCUMENTATION_SERVER.

Yes. If BOBRC environment is set, it should point to a path where to load the file from.
