Added some JSONP self test files (for tests of dynamic import)

[HolQue]

(Corresponding self tests coming soon.)

Short description:

• 5 levels of folders and subfolders ('dynamic_imports', 'AA', 'BB', 'CC', 'DD')
• on every level, 3 files:
  • <file_base_name>.jsonp (defining a level indicator key only, no further imports)
  • <file_base_name>.R.D.jsonp (defining a level indicator key and imports recursively another JSONP file using a dynamic path)
  • <file_base_name>.R.F.jsonp (defining a level indicator key and imports recursively another JSONP file using a fix path)
• dynamic_imports\global_defs\global_defs_1.jsonp defines some keys used for dynamic import

Use case 1 (fix path):

"[import]" : "./dynamic_imports/dynamic_import.R.F.jsonp"

Result (like expected):

DotDict({'level': 'DD'})

Use case 2 (the same like use case 1, but with dynamic paths):

"[import]" : "./dynamic_imports/dynamic_import.R.D.jsonp"

Result:

{'AA': 'AA',
 'BB': 'BB',
 'CC': 'CC',
 'DD': 'DD',
 '[import]': '... /dynamic_imports/AA/BB/imported.BB.R.D.jsonp',
 'level': 'AA'}

It can be seen that the computation of imports stops at level 'AA'. But also here level 'DD' is expected.
