+ Class DynamicQueryableExtensions
+
+ Provides a set of static (Shared in Visual Basic) methods for querying data structures that implement System.Linq.IQueryable.
+It allows dynamic string based querying. Very handy when, at compile time, you don't know the type of queries that will be generated,
+or when downstream components only return column names to sort and filter by.
