Enhancement: Add an 'Alias' property on the 'Field' object

[mikependon]

Describe the enhancement

In order to encapsulate the aliasing on the fields, it is better to add an additional property 'Alias' on the 'Field' object.

If this will happen, as a note to the internal development, all the implementations must abide with this new property, rather than explicitly passing the aliases as part of the method arguments.

var nameField = new Field("Name", typeof(string), "S"); // Coverted to S.[Field]

Note: There is no value on this request, and it MIGHT be a big change in general.
