* Improves Null Key Handling in Python
We aim to mimic the following behavior:
```python
>>> d = {1:2}
>>> None in d
False
>>> d.get(None) is None
True
>>> d.pop(None)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: None
>>> d.pop(None, None) is None
True
```

* Normalize universe data frames
Universe and (generically BaseDataCollection) data frames are not normalize and unpacked into a data frame, instead of just creating data frames with the universe lists within it
* Fix unit tests and algorithms to expecte new universe dataframe format
* Fixes
* Add PandasConverter.DataFrameGenerator class
* Pandas data frame generator class fixes
* Add comments
* Housekeeping
* Add attributes to mark classes and properties for pandas processing
* Improve pandas properties expanding
Allow and handle duplicate names
* Use PandasData generalization for Lean common data types
* Add points time as column when converting base data collections to data frames
* Cleanup and minor changes
* Minor change
* Pandas data to get type members on demand
* Move Pandas helper classes to their own files
* Minor changes
* Add flatten argument to python history api
This allows users to decide whether they want fully expanded dataframes for universe and other collection data types. Else, master behavior is kept
* Adding missing changes to last commit
* Update Pythonnet version to 2.0.40
* Add flattent argument to algorithm's OptionChain api
* Minor changes
* Housekeeping
* Minor changes
* Bug fix skipping data collection data points
* Add comment
* Set correct exchange time to OptionUniverse instances
* Address peer review and cleanup
* Cleanup
* Minor changes

* Adding unit tests reproducing issue.
* Fix a couple of minor bugs
- IsMarketOpen will work correctly when used with daily and hourly
resolution.
- slice.Get will work correctly with python custom data
- ExtendedDictionary will be able to dinamically access methods,
required for python and private C# data types
* Refactor solution. Add more tests
* Remove unrequired import statement
- Fixes:
- `Slice.GetValues`
Not returning the `Value` but the `KeyValuePair`
- `ExtendedDictionary.update(PyObject)`
Paramenter type should be `PyObject` not `PyDict`
- Adds unit test for `update()`
- Fixes `OrderListHash` of `PythonDictionaryFeatureRegressionAlgorithm` test.
Changes the return type of `keys()` and `values()` methods to `PyList`. Since `Keys` and `Values` return `ICollection` in some cases, the Python type was not consistently of `list` type.
