basic live coding techniques ("object style") without the use of JITLib
more to come..
using a simple environment. this looks just like ProxySpace, but works differently. for the difference, see link::Tutorials/JITLib/jitlib_basic_concepts_01:: and link::Tutorials/JITLib/jitlib_basic_concepts_02::.
