[Bug][HBL] Modulo operation on Matrix

[stevenweaver]

In HBL, an operation like this

a = {{1,2,3,4,5}{5,4,3,2,1}}
b = {{1,2,3,4,5}}
a%b

Will cause a segmentation fault. Perhaps it should fail gracefully.

[spond]

Yes, but better yet, it should work:)
This command is supposed to sort rows of a based on the column indices in b, e.g. if you have

a % {{1,2}}

this will sort a on column 2, and break ties using column 3.
In the example above, the indices of columns supplied in b are invalid (can be in 0-4), hence the fail. I'll fix.

[spond]

OK, it fails worse than the indexing issue (which I fixed in my branch). Keep open for now...

Fixed in version 2.12.
