Improve namespacing #3
Description
Currently our headers are nested in two folder in the root directory
hostapp
ruby
This has two problems
- The root repo path has to be added to the include search path, possibly confusing IDEs and compilers
- "ruby" conflicts with the actual ruby language headers, possibly confusing IDEs and compilers
This should be restructured to
include/hostapp
include/rubyutils
Additionally, even though all classes and functions well name-spaced, macros are not (eg: DEFINE_WRAPPED_METHOD)
Though the likelihood of naming collisions is low, it would be good practice to prefix all macros with SCA_ or something like that.
