ParseResult class abstract

The result of a parse operation, where

• ParseResult.none means the input did not satisfy the parsers predicate
• ParseResult.success means the parses succeeded without a parameter and
• ParseResult.value<T> means the parser succeeded with a T
• ParseResult.noValue means the parser failed where a parameter was expected

Note that there is no ParseResult.error or such, as a parser failing to match a segment just means that the next one is tried.
