Moelnir is a basic database file, addressing variable record data through
integer identifiers, which applies heap organisation of its data space.
Advantage of Moelnir is that each record is stored in a continuous
segment on the file while still record size is limit-less variable
and modifiable. There are no data length limits other than the range of a
63-bit unsigned integer. Scalability is limited to 1 - 10 Mio. entries due to
non-paging internal structures.
