Moves almost fully to relative placement of components.
- add ability to place a component by specifying location of its pins or principle coordinates.
- add ability to add offsets when placing components.
*This version is incompatible with previous versions.*
- location of component must be specified with named argument.
- ``orientation`` arguments have been renamed to ``orient``.
- terminal array (``t``) has been removed
You can upgrade previous schematics to this version by:
- adding ``C=`` to leading argument of all components.
- replacing ``orientation`` with ``orient`` in the argument lists of all components.
- replacing use of ``t`` with the actual names of the pins.
