[Square brackets] not grouping requirements properly #1285
Description
When generating prerequisite graphs, it seems like what reads the requisite strings does not seem to be taking [square brackets] into account. This causes MAT237Y1's graph to be completely empty.
MAT237's prerequisites:
[( MAT135H1, MAT136H1)/ ( MAT135H5, MAT136H5)/ MAT134Y5/ MAT135Y5/ ( MATA30H3/ MATA31H3, MATA36H3), MAT138H1/ MAT102H5/ MAT246H1]/ MAT137Y1/ MAT137Y5/ ( MATA30H3/ MATA31H3, MATA37H3)/ MAT157Y1/ MAT157Y5, MAT223H1/ MATA22H3/ MATA23H3/ MAT240H1/ MAT240H5
