Many instances of a local variable + named "case_num" were changed to "case_idx" as a consequence. + Many `struct ccase *' were changed to actual `struct ccase' + because of copying semantics of cases.

The linked list was + appropriate when we could stick a header onto cases, but that's no + longer the case. Also, the two-level array will allow for random + in-memory access in case that's ever wanted. Also added the + concept of a `destructive casereader', one that destroys cases in + the underlying casefile as they are read out. + (macro CASES_PER_BLOCK) New macro. + (struct casefile) New members `value_cnt', `case_list_size', + `case_acct_size', `being_destroyed', `cases'.
