- This commit is related to PR 19 in QC/pythonnet
- C# decimal will be cast to C# double and converted into python
float
- Adding new `decimal.py` into the python algorithm project. This is
required for backwards compatibility with users performing operations
over expected decimal types (like `Price`)
- Updating two python regression test algorithms using custom python
execution models to be aware and ignore floating point precision errors
when handling order sizing.
Implements `PythonExceptionInterpreter` that works as a "catch-all" exception intrepreter for `PythonException`. Since it can interpret more specific python exceptions that are already covered by other interpreters, its `Order` is set to `int.MaxValue` to be the last to be tested.
