Read object features table

[emilmelnikov]

Add the ability to read an object features table from object classification workflow.

Also, refactor and simplify all workflows and associated demos.

Closes https://github.com/ilastik/ilastik4ij/issues/56.

Are these changes backwards compatible (e.g. will old macros still run)? I've tried some of my old ones, but so far without success.

for Pixel Classification it seems that parameters have been renamed:

• projectfilename -> project
• inputimage -> rawdata

I know this sucks, I like the more expressive parameter names, too, but we can't break old macros because of an internal refactor

Good call, I forgot about macros.

Just to add now that I looked at the code it is really nice to see reduced amount of duplication and boilerplate for the workflows! I tested generating the tables and this works nicely as well. We'll have to add documentation for this though, as one has to configure the csv export in ilastik first - otherwise it won't work. The real power of the table can be unleashed once we allow for exporting the Object Identities. That way (I think) one could use feature table as colormaps (somehow) :D. We should maybe ask @tischi how to best do it and provide an example.

Would this work?

I presume we need to change table export in ilastik for this?

no, we'd need to allow exporting a different source via --export_source=Object Identities" command line argument.

that's perfect :) users don't even need to look into some docs.

Should we address this in a separate PR?
