Add a sector diversification option to AI Factors

I think adding an AI Factor option that would be applied after Validation, that would then allow a second sorting of Portfolio Quantiles, called Portfolio Quantiles Sector Maximum Exposure, would be extremely useful. This would be a number like 25, which would allow no sector to make up more than 25% of a quantile. Also a chart like the one that appears on the Results / Returns page, just liek the existing Average Number of Stocks in Buckets, but instead plotting Average Number of Stocks per Sector, would be helpful. Thanks
