Add a Project/Select From Set Activity

It is common use case to need to get a common list of properties from a set of features or objects. Similar to how Get feature Object IDs works.

Thus it would be great to have a Select From Set activity to which takes an expression for projecting a set into another set. Similar to Linq.Select in C#

For example if you had a set of features you could provide a selection function to get some property from them and return it as an array.

Select Lambda:

=$item.attributes.GLOBALID
