* Implements Equity Fill Model
This commit sets the base to create a new equity fill model and the `EquityFillModel` is just a copy of `FillModel`.
* Adds Summary to FillModelPythonWrapper.GetPricesInternal
Adds summary to FillModelPythonWrapper.GetPricesInternal with remarks that it's a temporarily method to help the refactoring of fill models.
- Adding _some_ of the missing PyObject.Dispose calls. In the cases
where C# is calling the Python side.
- Note that Python calls to C# code is correctly handling the
disposure of resources.
- Modifying `IFillModel` interface removing old methods and adding new
method `Fill Fill(FillModelParameters)`. This is a breaking change.
- Adding new `PythonWrapper` property for the `FillModel` base class.
This is required due to a limitation in PythonNet:
- Given C# class T has `virtual` methods A and B. Where method A
calls method B. And given custom python class L inherits class T.
And overrides method B. When class L calls
base method A (of class T). And when method A internally calls method B.
It will call C# implementation, not the python override. This issue
is solved going back to the `PythonWrapper`. Adding unit tests.
- Adding new `Parameters` property for the `FillModel` base class that will
be set by the call to `Fill()`. The `Parameters` property will be used by
the modified `XxxxFill()` implementations
- Adding new `Fill` result object for the `Fill(FillModelParameters)`
method
- Adding new check before removing a `SubscriptionDataConfig` due to the FillModels consuming the configuration collection when determining which Price to use. WIll now only remove the `SDC` if the symbol was removed from the selecting `universe`, this will avoid the case where the symbol is never deselected and the subscription ends, which happens at the end of all executions.
- Adding unit tests showcasing retro compatibility.
- Enabling C# `CustomModelsAlgorithm` as a regression test. Python
version returns a different result due to random number generation.
Summary of members in python wrapper classes where pointing to other methods for reference when they should have a meaningful description to be used in documentation
Adds support for fee, fill and slippage custom modelling.
Adds CustomModelsAlgorithm to showcase the new feature
Modifies C# version of CustomModelsAlgorithm to match existing data in github
