Points are now weighted on a test context basis In particular, this has allowed for simple extensions to the format of testconf to award points to whole test groups without at the same time compromising the future ability of giving partial score for correct but slow solutions. Specifically, the groupweight configuration variable has been added and normally has the format {groupindex: points} where groupindex is the group's index in the tests configuration variable. The backwards incompatible change is that test contexts are no longer guaranteed to learn the score awarded or the maximum possible score for every test case and may instead be notified about them in batches. In other news, the pointmap and groupweight configuration variables can (now) be given as sequences in addition to mappings. (Technically, the distinction currently made is dict versus everything else.) Items of a sequence pointmap/groupweight correspond directly to the test cases/ groups defined in the tests configuration variable; in particular, when groups are used, tests=[1],[2,3];pointmap={1:1,2:2,3:3} can now be written as pointmap=tests=[1],[2,3]. Missing items are handled in the same way in which they are handled when the variable is a mapping. Note that the items of groupweight correspond to whole test groups rather than individual test cases. In other news again, the wording of problem total lines has been changed from '<unweighted> points; weighted score: <weighted>' to '<weighted> points (<unweighted> before weighting)', and group total lines now properly report fractional numbers of points (this is a bug fix).
