Subject: [branch] and [flatten] support  (#2928)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Small fixes and improvements around reflection tool.

* Make PrettyWriter printing a class.

* Add HLSL output support for [flatten] and [branch]

* Handle [branch] on switch.
