    Retrieves all possible chainTips from the database.

    Retrieves all possible chainTips from the database. Note this does NOT retrieve the BEST chain tips. If you need those please call getBestChainTips. This method will search backwards appConfig.chain.difficultyChangeInterval blocks looking for all forks that we have in our chainstate.

    We will then return all conflicting headers.

    Note: This method does NOT try and remove headers that are in the best chain. This means half the returned headers from this method will be in the best chain. To figure out which headers are in the best chain, you will need to walk backwards from getBestChainTips figuring out which headers are a part of the best chain.

    We need to cast from TableQuery's of internal types (e.g.

    We need to cast from TableQuery's of internal types (e.g. AddressDAO#AddressTable) to external versions of them (e.g. AddressDAO().table). You'll notice that although the latter is a subtype of the first, this requires a cast since TableQuery is not covariant in its type parameter.

    However, since Query is covariant in its first type parameter, I believe the cast from TableQuery[T1] to TableQuery[T2] will always be safe so long as T1 is a subtype of T2 AND T1#TableElementType is equal to T2#TableElementType.

    The above conditions are always the case when this is called within DAOs as it is only ever used for things of the form TableQuery[XDAO().table] -> TableQuery[XDAO#XTable].
