I've worked a bit on the previous draft (#63) of the nvm tree variant of haura's nodes to improve performance. This is the current version of this endeavour. Performance is improved on the new variant of the tree as well as the old "block" variant due to various performance fixes in the entirety of the storage engine. Additionally,

Oh, and we allow for yaml configs because i don't want tofoo: {{{{{[[{ option: null }]]}}}}}anymore.Also some crucial bugs are fixed related to the node balancing in haura. This PR arguably fixes some problems which have existed some time related to the
epsilonof ourb^epsilon.Compression still needs to be integrated with this variant of the tree as well as some safety checks.
