Return the type of a given bel.
### const\_range\<std\:\:pair\<IdString, std::string\>\> getBelAttrs(BelId bel) const
Return the attributes for that bel. Bel attributes are only informal. They are displayed by the GUI but are otherwise
unused. An implementation may simply return an empty range.
### WireId getBelPinWire(BelId bel, IdString pin) const
Return the wire connected to the given bel pin.

isn't used by any of the core algorithms. Implementations may
simply return `IdString()`.

Return the attributes for that wire. Wire attributes are only informal. They are displayed by the GUI but are otherwise
unused. An implementation may simply return an empty range.
### uint32\_t getWireChecksum(WireId wire) const
Return a (preferably unique) number that represents this wire. This is used in design state checksum calculations.

Get the X/Y/Z location of a given pip. Pip locations do not need to be unique, and in most cases they aren't. So
