* config loads and reads the config file in the init method to reduce io operations
+ get method is now able to take 2 optional arguments, a request key and a definable default value
+ add config.py to read / touch create the etc config file
_read():
tries to open the config files in read only mode to parse its contents.
_check():
checks if the config file is present and then calls _read()
if that is false it tries to touch create a new file.
worst case scenario: file is present and holds content, the method assumes that the file isn't present. Therefore tries to touch-create a new file, if a file is against all odds present, only the mtime would be updated. Hence any file content would not be altered.
get():
main method, calling _check()
if a key is given return only the assigned value or None
or return the whole dictionary
