Multiple data fields

OBS: The destination branch is currently set to master. This perhaps should be changed to development?

This merge request generalizes functions and classes in the database_interface and audio_loader modules to handle multiple audio representations (i.e. for the same audio clip, multiple representations are generated). For example, it is now possible to call the create_database method as follows,

    rep1 = {'type': 'Waveform'}
    rep2 = {'type': 'Mag', 'window':0.5, 'step':0.1}
    di.create_database(output_file='db.h5', data_dir='data/', selections=sel_table, audio_repres=[rep1,rep2], data_name=['wf','spec'])

This will create an hdf5 database with a table that has two data columns named wf and spec which contain waveforms and magnitude spectrograms, respectively.
