#2697:

• removed AlglibUtil.cs and added an extension method .ToArray(names, rows) to IDataset instead.
• refactored transformation so that it is possible to apply an transformation without resetting the parameters
• Used transformations instead of Scaling as far as possible.
• Moved TakeEvery extension method to HL.Common
