[orbitcpp-list] string-template test directory

[Phil d. <ph...@us...>]

Hi Andrew, all,

I've split the string test into 2: string-template and string

The string-template directory will take the role which the string test
used to have - to develop and try out hand coded stubs and skeletons
which serve as a target to build the idl compiler to. 

The string test directory will be a proper test which uses the idl
compiler to build itself. The stubs and skeletons produced will
approximate the ones in the string-template test directory.

Eventually I will remove the string-template directory when the idl
compiler is mature enough.

Cheers,

Phil.
