Notes
* Due to the limitations for how Boxed_Value is handled
the unique_ptrs must still be wrapped in a shared_ptr
* However, this caveat does not directly affect the user
Temporaries created during user conversion operations were being dropped
before the result of the conversion was able to be used. This fixes that
by temporarily storing the result of the conversion inside the
current Function_Push_Pop context.
This line of code does not cause an error on clang-3.4 or clang-3.5
on Linux. Apple's clang is somewhere between the two, no way to know
where.
For an unknown reason, specifying default move operations in 'Data'
causes the compiler to think that Boxed_Value is an incomplete type.
This is highly illogical since Data is only used via a shared_ptr, so
the size / type of Boxed_Value should be fully known (and is known on
every other compiler/platform combination).
Needed 1-2 cleanups by hand. 99% was automatic.
* The version that ships with ubuntu 14.04 seems to not work.
I had to build from scratch
* Use cmake to generate the build commands that clang-modernize wants
```sh
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS:bool=true ../ChaiScript/
```
* Use the clang-modernize tool. Note that you have to be pretty explicit
about the include paths if you want it to also update your include
files
```sh
../llvm-build/bin/clang-modernize ../ChaiScript/src/*.cpp -for-compilers=gcc-4.8 -include /home/jason/ChaiScript/include,/hjason/ChaiScript/include/chaiscript,/home/jason/ChaiScript/include/chaiscript/dispatchkit,/home/jason/ChaiScript/include/chaiscript/language -p compile_commands.json
```
* In my case, it left some unused `typedef`s behind, which I cleaned up.
- ChaiScript no longer includes or automatically instantiates std lib
- ChaiScript constructor now requires an std lib instance in the form
of a ModulePtr object
- This new layout facilitates better usage of compilation firewalls and
factories for reducing the overall impact of ChaiScript on a project
