Add new Blueprint examples (#68)

- Adds a script - json_string_compiling.php running the Blueprint from a
string containing a JSON.
- Creates the 'examples' directory to group all nonessential scrips
added to showcase the lib's capabilities.
- Moves the blueprint_compiling.php script to the 'examples' directory.
- Fixes scrips to run with PHP >= 7.0.
