Add Transforms to Properties

[eeverman]

Is your feature request related to a problem? Please describe.
It would be nice to not have to be picky about capitalization. If a value must be 'FOO' or 'BAR', couldn't there be a post-parse step that would accept a transform to convert the value to UCase?

Similar things could happen for other types of values: Round to the nearest X, absolute value, etc.

Describe the solution you'd like
A transform step, that happens after parse but before validation.

Describe alternatives you've considered
Types can be used to do this during parse, but its more involved and easy to break contracts. Easier to have a simple transformer that anyone could plug into with a lambda.
