multi project build file. basic structures seems right. we'll have the xml's published as a jar, then the api, then core which will be filled with sources produced by gen. probably we'll have to add back RichNumber etc. to core because that stuff will be used by default values from the spec
use 2.10 for api and core
compiles all 2.10 -- not sure if scala-refactoring does the right things, still, though....
generator task should be correct; but not tested
next step... somehow the api library is not found in core?
ok, that was it (missed on directory). now indeed we need implicit Float => Constant and the GE ops
that went through. do away with 60.midicps default args for now, and use nyquist (which is anyway better) as a special value.
