`InputList::push` is useful for building up an `InputList` in operator tests. At the same time, update the documentation following the change to make `InputList` a copy-on-write data structure.
At clippy's request, add this impl.

This initial implementation is limited to supporting equations which can be implemented as a single matrix multiplication, with permutation of the inputs and outputs if needed. This is sufficient to support the Einsum operations that appear in Segment Anything [1] models. Simple transpositions are also supported. [1] https://huggingface.co/facebook/sam-vit-base
This takes an image and a query point as input and outputs a segmentation mask.

Add an initial version of the
Einsumoperator, and a Segment Anything model example, whose image encoder model requires it.The initial Einsum implementation is limited to equations that can be efficiently executed as a single matrix multiplication, with permutations of the inputs and outputs if needed.
The example uses the sam-vit-base model variant in its documentation, but I have also tested with sam-vit-large and slimsam.
