Prettify ToString return value

[AlexanderButs]

Tried to do as best as can. Any comments are appreciated.

@AlexanderButs This puts the original expression at the schedule level when it should really be at the field level so it solves the problem but partially. I think the expressions should be captured at the field level and the schedule should then just call ToString on each of its fields.

Also, the author/committer for 26ffc8bc08e1cc39737b690ca1a078fb642271ef reads unknown <[email protected]>, which seems not what you'd intend.

Thanks for Your feedback. I'll try to look at this.
