Big commit containing detailed schematic, BOM, a lot of glossary
entries, truth tables and references to the datasheet of the parts
mentioned in the schematic.
The change includes some labels in pre previous referred chapters,
some clarifications in the referred images, some glossary entries,
two online datasheets in the bibliography and block diagram
of a proposed client node schematic circuitry.
The power factor and the phase angle was unclearly related.
This problem was fixed by removing the problematic formula,
reformulating surrounding sentences and adding the citation
to support the fact.
The topic was changed to its final form from the working name.
Minor clarifications of some lines to reflect the latest notes from the consultant.
The note about Roman letter highlights in figures from HW requirements.
