**THIS VIOLATES THE RULE OF NOT CHANGING THE LOCATION OF PINS!**

Enable all passives to be the same length, 400 mils seems to be the
smallest reasonable size.

These are not actually a part of the license itself (but Creative Commons

First Power Symbols version 2

See merge request !12

It should be the only library which is not an English plural noun as
KiCad needs it to be named exactly power.lib.

Pins should be named the same as the symbol but the numbering isn't that
important.

Pins should be set to not be visible in order to follow the KiCad
requirements for being a power net.

Schematic capture by default uses a 50 mil grid, so keeping symbol pin
ends on that grid should work well and provides more flexibility when
creating symbols.

But keep pins spaced 100 mils from each other so that having pin texts
which indicate the pin number sized at 50 mils does not look silly.

This required a renumbering of many of the schematic symbol rules.

60 mil for field texts is the default, so use it to ease development.
Other texts can easily have a default text size of 50 mils (this setting
is often retained from part to part once changed once by the user) and
it looks nice, so use it.

Use "should" rather than "shall" as there may be cases where the text
sizes may necessitate being different, but this should be rare.

Start symbols

No actual symbols yet, just infrastructure.
KiCad really wants to have a project, schematic, and layout.

Ignore files ending in "bak" and files with "cache" anywhere in their
name.

These files are required to exist for the project in order to edit
symbols and footprints but do not actually capture any schematic or
layout in them.

Signed-off-by: Andrew Bradford <andrew@bradfordembedded.com>

With these files in place, we should be able to create schematic symbols
and footprints (modules).

All default KiCad libraries have been removed from the project,
schematic, and layout.

Readme footprints v2

Builds upon merge request !3 but with corrections discussed.  Adds two new commits to cleanup symbol grammar and clarify that symbol pin locations must not be changed due to KiCad current operation.

See merge request !4

To avoid situations where this git repo is updated causing schematic
nets to break due to symbol pin locations changing unexpectedly.  KiCad
does  not cache the symbols within the schematic itself (which is unlike
how footprints are often cached within a layout itself so that in order
to cause a change to a footprint that the newer version of a footprint
must be imported by the user in an explicit operation).
