DSP: framework build fixes for iOS. see #119.
Foundation lib: added all of the newer source files to the iOS project -- highlighting the impossibility of maintaining this project separately from our YAML projects...  see #119.
all libs for iOS now build their static libraries (.a files) to the same build folder as the other architectures to make things more consistent and easier to find (and have fewer permissions issues). see #119.
Graph: organizing Xcode project so it is easier to see what is missing when there are updates. see #119.
AudioGraph: commenting out the prototype for the unit test -- there is apparently no test method actually implemented which causes linker errors on the iOS example projects. see #119.
