Variant names can not contain digit characters

[pblasucci]

Description

Generator fails when variants contain digits.

Repro steps

Please provide the steps required to reproduce the problem

1. Define a sum type as follows: union Choice<T,U> { Choice1Of2<T>, Choice2Of2<U> }.

Expected behavior

Produces appropriate Choice, Choice1Of2, and Choice2Of2 classes.

Actual behavior

Fails silently on command-line. If Run Custom Tool is chosen in Visual Studio 2015, display a dialog box with a parsing error.

Known workarounds

Don't use digit characters (0-9) in variant names. In other words, union Choice<T,U> { ChoiceOne<T>, ChoiceTwo<U> } will work just fine.
