Grassmann.jl also supports the Hestenes/Dorst interior product

Is there a specific example that can be tested?

@chakravala

The following are inconsistent results from ganja.js, which demonstrate that their definitions are inconsistent, which makes them incompatible with original Grassmann.

The first two results here are supposed to be equal to each other (-e13), while the third result is supposed to be positive (e123), demonstrating there are issues with their definitions and is not compatible with Original Grassmann.

Here is an example with ganja.js, I do not know if this example is representative of all authors, this is just one particular example I have discussed before.
