Enigma mappings improve 2

[Janmm14]

Rewrote the parser.

• Still using indices for fast string parsing
• Fixed inner classes again
• Should be able to create better error messages
• Improved tolerance for bogus spaces
• Basic indent validation
• No state machine, state is handled by code flow

Please give feedback on complexity and maintainability.

It seems to a little faster than the previous one. Speed about the same as the previous new impl.
Due to lambda usage MemberMappingsConsumer for code clarity, first shot speed is a little slower.

Please give feedback on complexity and maintainability.

Compared to the prior state-machine based system, this is much easier. I was able to read through the utility methods and easily fill in doc comments.
