Original Issue: Missing adobe::move_from

The master branch used move_from but I am unable to find it in the source code. Is this an error or been replace?

adobe_source_libraries/adobe/poly_regular.hpp

Lines 63 to 67 in 5ced8bf

	/*!
	Move constructor
	*/
	poly_regular_instance(move_from<poly_regular_instance> x)
	: base_t(move_from<base_t>(x.source)) {}

[Levi-Armstrong]

It looks like these constructors should be updated to leverage be the following now.

poly_regular_instance(poly_regular_instance&& x) 
         : base_t(std::move(x))) {}

This header and its corresponding test do not seem to be part of the CMake build at all, which explains why I don't get any compilation errors coming from this clear error.
