the core library of my nrs implementation.
this provides data structures (Entry, Impact, Relation, etc.) and
functions to operate on them, as well as some togglable extensions.
since this is an implementation, it describe a nrs system, not a core system,
many extensions like DAH_entry_id, DAH_entry_id_impl and DAH_meta
are implicitly enabled (these extensions can not be disabled), which means
that the non-extension specific code may not be able to integrate into
a generic nrs implementation (which basically does not exist because only
i have mental illness).
this thing is licensed under gplv3 because autism
