[Feature] Provide a toString() method for enumerated values in Java

[jeromesimeon]

It would be convenient to provide a way to easily get the string name for enumerated values. For instance to get the name of a currencyCode as a Java String.

Context

It's not a bug, but feature request.

Expected Behavior

Calling myEnum.toString() should return the name of the enum as a Java String.

Actual Behavior

The application has to create string representations (e.g., through myEnum.name()) by hand.

Possible Fix

Add a toString() method for enums, maybe using .name() for enums.

Steps to Reproduce

Context

Working on an application where CTO models are generated to Java with additional fixes for the Corda network. Monetary amounts CTO representations which include an enum for currency codes are converted to Java Currency classes.
