Remove demos/MoodTagger

[alastair]

This demo has lots of hard-coded paths, is windows-based, and relies on remote controlling winamp. There's also no documentation, it seems like it might be better to just remove it rather than try and make it work.

Other files that could be removed:

• src/bindings/pygaia/essentia.py
• src/bindings/pygaia/Gaia2 Python module.e4p
• src/bindings/pygaia/mtgdb (replace with an MTG-specific repo, keep this out of gaia)
• src/bindings/pygaia/linalg (doesn't seem to be used, some other stuff uses linalg package from numpy)
• test/scratch (a bunch of experiments? put them in a better place if they're good)
• scripts/classification/generate_essentia_models.py, generate_classification_project_mtgdb.py
• scripts/collections (is this specific to our collections too?)
• rpm build file
• deb build

Agreed, MoodTagger should be removed in a separate PR.

We now have a repository with the scripts we are currently using to build MTGDB models:
https://github.com/MTG/mtgdb-models

Therefore, src/bindings/pygaia/mtgdb and src/bindings/pygaia/essentia.py are also obsolete.

One thing missing in the new repository is a default list and metadata of the datasets (see DATASETS_DATA and DATASETS_GROUNDTRUTH variables). Perhaps those could be added or document better DATASETS_DATA and DATASETS_GROUNDTRUTH in the README instead? @pabloEntropia

The code in scripts/collections should be also removed. Again, we need make sure that the new repository does have similar consistency checks when training the models to ensure that all training collections are valid (e.g., no missing audio files with respect to the ground truth metadata). I would expect that this is so already, please confirm (@pabloEntropia).

Get rid of scripts/classification/generate_essentia_models.pyand generate_classification_project_mtgdb.py too.

I would create a separate issue for test/scratchand those can be recycled to make a nice jupyter notebook tutorial for similarity and classification in Gaia (a task for me).

[dbogdanov]

src/bindings/pygaia/linalg contains a helper function for the Gaia's PCA. It's not used in the examples, but it can be useful. Perhaps to be merged with other helper functions we can come up with after writing a tutorial.

[dbogdanov]

Get rid of src/bindings/pygaia/Gaia2 Python module.e4p too.

[alastair]

reopening because we have a few other pending items here to finishing

[dbogdanov]

Everything is addressed in expect for rpm build and deb build files (open a new issue for them).

Fixed in #121
