This is a zero-dimensional object that can be used for snapping
and documentation of useful, but non-physical features on a
board or footprint. They do not correspond to any physical
output in exports or plots.
Points do have a "size", but this is a graphical property only
and determines how large they are drawn on the board.
They also have a layer, which allows them to be selected and
made visible according to layer filters.

Footprints can now have a custom stackup. This means that they specify
an exact number of copper layers and the layers map 1:1 to board layers.
If the board doesn't contain that layer, the element just doesn't
show. We could make this a DRC check later on.
If there is no stackup, the behavior is the current default: a rule area
the In1 layer "expands" to all Inner layers.

Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Probably this should be replaced with a less error-prone
approach. Right now the LSET -> BASE_SET system is risky
because it is converting a signed enum (PCB_LAYER_ID) to
a size_t in all the underlying operations.

F_Cu = 0
B_Cu = 2
Remaining internal copper layers are even and incrementing
Non-copper layers are odd and incrementing.
This means that we can no longer do things like:
for( PCB_LAYER_ID layer = F_Cu; layer <= B_Cu; ++layer)
Instead, we have the class LAYER_RANGE:
for( PCB_LAYER_ID layer : LAYER_RANGE( F_Cu, B_Cu) )
Similarly, gt/lt tests should not refer to the integer value of the
layer. We have functions such as IsCopperLayer to test whether a layer
is copper or not.
When using the connectivity RTree, the third dimension is layer, so we
provide B_Cu with the special INT_MAX value, ensuring that elements
between F_Cu and B_Cu will be identified. There is a new, special
function GetBoardLayer() for interfacing with CN_ITEMS
Similarly, PNS layers remain unchanged and sequential. A set of
interface functions is provided to map PNS layers to Board layers and
back. This allows the PNS_LAYER_RANGE to function as expected
We are derived from std::vector now. We don't need our own prima donna
increment and dereference overload as these just create bloat and
non-standard coding practices
The old bottom to top layer stack up sequence from back to front layer was
only used for plotting so it was renamed appropriately. This will be used
for future board object select disambiguation improvements.
We only need one bottom to top layer sequence definition.
Plot a sequence of layer IDs (LSEQ) in the order of the sequence.
Add helper method to layer set (LSET) to create a sequence of layer IDs
using another sequence for ordering.
