TODO for v0.2

• Finish converting schema from /schema into human-readable docs (just have the appliance_model to convert, I think)
• In each Appliance or ApplianceType, components should be specified as Appliances not ApplianceTypes. i.e. use type instead of parent.
• copy info from catalogue into UK-DALE
• re-do UK-DALE using new schema. Send to UKERC EDC.
• write docs
  • how to write your own schema
    • find appliance names
  • how to add data to common metadata
• convert other datasets: REDD, HES etc. I guess these should go into nilmtk/dataset_converters/redd etc
• Modify code (a lot) so that it gets rid of all validation stuff.
• rename 'objects' to 'appliances' (seeing as it only contains info about appliances). Rename links in dataset_metadata.rst
• tool to generate graphical model of relationship between objects in /objects and also in a dataset metadata
• fold project into NILMTK (we don't want this to be a requirement for NILMTK, surely)
• allow NILMTK to load common appliances data
