pass C++ variables into Cling

[blockspacer]

If you want to use cling, maybe following will be useful:
https://github.com/blockspacer/CXXCTP/blob/master/src/template_engine/engine_main.cpp#L20

Note argRefToCling function, it allows to pass C++ variables into Cling (or maybe it is possible to do it easier).

// Or use macro / codegen
#define ARG_REF_TO_CLING(varType, varName) argRefToCling(varType, #varName, (varName))

Also note that usage example is reflection/codegen engine ( https://github.com/blockspacer/CXXCTP ), may be useful for game engine/level editor/e.t.c.
