xcode: Deleted trace file. 

Its not needed, and its very large
TypeManager: ReadWrite doubles via void* with emscripten

With simple pointer cast  emscripten does not wolf ( as go 1.16.0) Using a memcpy works fine.
Makefile, Datatype.h: Now using stdint.h fixes warning with emscripten

Now using standard definitions for INT16_MIN,... macros
Compiling with optimization at -0s now works.
Whitespace, comments: Some cleanup while fixing emscripten build.
Merge branch 'incoming' of github.com:PaulAustin/Vireo into incoming
Cleanup: Removed experimental xcode project "VireoCanvas"
web: Put emscripten makefile in separate folder, some html work
Adding some useful entry points for type reflection
use POSIX_NAME macro to make vs2012 happy.
web: More experimental html page to load emscripten version of vireo
Merge branch 'incoming' of github.com:PaulAustin/Vireo into incoming
web: VireoNest work
Time:  Time tracked in host resolution, TicCount => TickCount, Linux wraparound fixed

Some hosts use milliseconds, other micro or nano, other user raw clock like 666.66.. MHz. Before resolution
was limited to microseconds, and extra calculations were necessary every time the wakeup list was checked.
Now only an single Int64 comparison is needed.

int32 arithmetic used in Linux #ifdef was promoted to int64.
Web: added examples
makefile: change optimization level, .gitignore
Samples: Updates to PID VI ( not in via format)
Time: ExecutionContext changes the were omitted in the last commit.
make: Removed extra <stdint.h> includes added __STDC_LIMIT define, unix make file tweaks

Fixed empty folder unit test bug. Folder was not included as part of repo, now it is.
make: Added pthread to unix link, documented "simple" target
