Header file name clashing

[bruno-j-nicoletti]

Seperate modules within the elements project contain header files with the same name. For example both artist and elements have a header file in their include dir called infra/support.hpp. Which one you get will depend on the include path order of the build. This will cause errors.

A suggestion is that you namespace header files to avoid that kind of problem. So something like infra/artist_support.hpp for artist and infra/elements_support.hpp for elements.
