[Bug ?] repeated wedge product causes weird out of bounds error

@basis "1,1,1,0"

#plane in PGA3D

probably related to some terms ending really close to zero but not exactly zero

Fixed the error just now on my laptop, but need to sort through some other uncommitted changes before I make a new commit.

Another thing to consider is forcing exact zero on + and - operations even if it is approximately zero.
something along the lines of
-(A,B) = isapproax(A,B) ? 0 : A-B
to avoid numeric noise

The issue is now resolved in the newly released Grassmann v0.7
