"""Create a mirror object from the provided list and line.
It creates a `Part::Mirroring` object from the given `objlist` using
a plane that is defined by the two given points `p1` and `p2`,
and the Draft working plane normal.
Parameters
----------
objlist: single object or a list of objects
A single object or a list of objects.
p1: Base::Vector3
Point 1 of the mirror plane. It is also used as the `Placement.Base`
of the resulting object.
p2: Base::Vector3
Point 2 of the mirror plane.
Returns
-------
None
If the operation fails.
list
List of `Part::Mirroring` objects, or a single one
depending on the input `objlist`.
To Do
-----
Implement a mirror tool specific to the workbench that does not
just use `Part::Mirroring`. It should create a derived object,
that is, it should work similar to `Draft.offset`.
