<=>(other)

We compare UnwindDetails when choosing which state to unwind to. If two options have the same state_index we prefer the one most removed from a requirement that caused the conflict. Both options would unwind to the same state, but a `grandparent` option will filter out fewer of its possibilities after doing so - where a state is both a `parent` and a `grandparent` to requirements that have caused a conflict this is the correct behaviour. @param [UnwindDetail] other UnwindDetail to be compared @return [Integer] integer specifying ordering

all_requirements()

@return [Array] array of all the requirements that led to the need for 

   this unwind
reversed_requirement_tree_index()

@return [Integer] index of state requirement in reversed requirement tree 

   (the conflicting requirement itself will be at position 0)
sub_dependencies_to_avoid()

@return [Array] array of sub-dependencies to avoid when choosing a 

   new possibility for the state we've unwound to. Only relevant for
   non-primary unwinds
unwinding_to_primary_requirement?()

@return [Boolean] where the requirement of the state we‘re unwinding 

   to directly caused the conflict. Note: in this case, it is
   impossible for the state we're unwinding to to be a parent of
   any of the other conflicting requirements (or we would have
   circularity)
