template project code automatically generates output folder if it doesn't exist.

[elmbeech]

update to the template project, so that code automatically generates the output folder if it doesn't exist.
this solves issue MathCancer#183.

additionally, i added an std::endl; to the final standard output line that was missing.

On Windows, using MinGW64, I'm seeing:

on hold until it's multi-platform

[elmbeech]

ok! i understand. still try to fix this, inclusive a unit test for all platforms.

[elmbeech]

ok, @MathCancer , I merged @drbergman 's Github action to build and run template project on all 3 OS #241 this code and now have a version that seems to compile on all platforms.
I will make a new pull request.

• https://github.com/elmbeech/PhysiCell/tree/patch_output_folder

The code as such looks like this:

#if defined(__MINGW32__) || defined(__MINGW64__)
mkdir( PhysiCell_settings.folder.c_str() );
#else
mkdir( PhysiCell_settings.folder.c_str(), 0775 );
#endif

This works because we assume the PhysiCell Windows user to run g++ MINGW.
Frankly, even if this passes the tests, I not completely see through if this is really water tight.

I checked manually on Linux and it does the trick!
@rheiland could you please try the same on Windows and Macos ?

make data-cleanup clean reset
make template
rm -r output
./project 

Thank you, Elmar
