Checkit Import into Brightspace (D2L)

[owensks]

When importing the problem database from CheckIt into Brightspace, the subscript numbering on VS9 tends to loop after three occurrences. So x_4 shows up as x_1, x_5 shows up as x_2, etc. Sample below.

I think the pattern is that for three or fewer variables, things are OK, but whenever there are more than three, the looping happens.

This is a more general bug (that happens only sometimes and we're not sure why). I'm hoping it comes out in the wash of an update to 0.2 but will investigate further if not.
