Version 3.0

What's Changed

• Now module will be called config_framework when you import it into project
• Structure of whole project is different comparing to 2.0
• Usage of VariableKey to create key that will tell how to access nested values
  without worrying about what symbols to use, but requiring to explicitly write
  VariableKey whenever you want to go from this root key
• Improved usability by using descriptors and making more logical arguments order
• By default, config will not allow you
  assigning any values after __post_init__ was called
• Version 3.0 by @Rud356 in #10
