Resolves #717

My comment: any names here are temporary, feel free to change them:) I only wanted to create a new structure.

@JeanPaulShapo, I know about warnings, the messages file will be updated and added in some section in future, maybe in devguide.

We had Appveyor build problems at least for week.
In particular, there were errors connected with improper slashes
in path naming while finding Boost library (Boost expects Unix-way /,
found Windows-specific \).
The solution has found in interesting discussion on CMake issue-tracker
(https://gitlab.kitware.com/cmake/cmake/issues/16670):
specify type of Boost variable provided when invoking `cmake` command.

As far as I know, we can't guarantee order of rows & columns
in `pandas.DataFrame`, which represents our Phi matrix.
That's why, in order to make proper comparison, I decided
to create `pandas.DataFrame` for reference data.

Fix two bugs in in-memory processing:
- bug with deletion of corresponding BV
- bug in artm.ARTM.transform with such BV
- minor code refactoring

* Fix documentation typo
* Fix title underlines in documentation to remove
warnings during documentation building

Perplexity refactoring for dealing with modalities.

New regularizer for smoothing time in topics was added

Model Saving From Python API
+ add score_tracker import/export in cpp code
+ fix config issues in scores anr regularizers in python api

Code refactoring:
- all unnecessary doubles were replaced with floats
- everywhere if and for statements are using with brackets
- use const qualifiers for references in range based for
- replace guard headers with #pragma once (update cpplint)
- some code decoration in regularizers and scores

Add NetPLSA regularizer.

* add ability to re-morm values in dictionary while filtering

* fix bug with df_rate (num_items would not be lost during import and filter any more)

* BatchVect should not gather dictionary when loading ready batches

* shameful bug fix in docs

* * Python 3.x support for hierarchical topic models
* Fix bug in hARTM.load(...) -- models saved with hARTM.save(...) didn't load before

* Re-structure imports in hierarchy_utils.py

* Allow passing sparse matrices to _parse_n_wd()

* Relax constrains on diff between old and new perplexity and sparsity values in dump-load test

This reverts commit abee373.

* Allow passing sparse matrices to _parse_n_wd()

* Loosen the test threshold

* Improve Python docs

- add autodoc about recently added regularizers
- briefly describe changes in Python API

* Add ``scipy`` dependency into Python docs

* Bump BigARTM version number to v0.9.0

* Update links in downloads section
