- Adding new `AlgorithmSettings` Min and Max absolute portfolio target percentage - Adding new `PortfolioConstructionModel.FilterInvalidInsightMagnitude()` helper method that will be used by the `BlackLitterman` and `MeanVariance` optiomization portfolio construction models to skip insights with extreme magnitudes that will cause exceptions - `PortfolioTarget.Percentage()` will now verify requested percent is withing the settings values
