one more STEP
- build fixes
- dependency fixes for expparse / expscan.
- handle newer clang compilers
- more robust parallel building
- relocation of headers and explicit directory prefixes
- client codes should now include one directory (for example, /usr/include/stepcode) and specify headers in their code using path/header.h - (for example, #include <clstepcore/sdai.h>)
- previous releases required explicit listing of all stepcode folders due to internal header include directives - this has been corrected
