These utilities represent a collection of functionality requirements that crop up from time to time in numerical and statistical contexts. Some examples of current functionality:

• Deep copies of collections of objects, e.g. for task local storage
• Two key dictionaries that don't require you to declare extraneous Tuple keys
• Symmetric two key dictionaries that don't care about the ordering of the keys
• Sorting, scaling, standardizing, normalizing, percentile-izing of collections of doubles
• Standard deviations and variances for collections of doubles
• Drawing random elements from a dictionary representing a probability distribution
