IQueryable Select

[Odonno]

Offer a way to query table records with better performance using the IQueryable<T> interface, somewhat paving the way for an EF Core implementation.

• Return IQueryable<T> instead of IEnumerable<T> for Select method, or IOrderedQueryable<T> that offers sorting features, if possible
• Create a custom query builder and use it build to a string query
• Avoid usage of query builder if not needed (on full table projection)
• Add tests
• Create an example project to showcase some basic features (filtering, grouping, counting, ordering, projecting, etc...)
• Update documentation with some examples/use cases

Even without EF Core, IQueryable with .Where and .OrderBy would be invaluable and expected in the .net world.
