#############################################################################################################
## inputSetUp matrix contains:
# line 1: (C11) the index for the order of the test (zero entry if we did not have a first test yet), (C12) SampleSize, (C13) alpha, (C14) M, (C15) base(the line of p where the looping will start in the next test), (C16) title, (C17) reject (the index indicating if and when H0 was rejected), (C18) pho (zero if Wald is used), (C19) Tailed (1 for one-sided test and 2 for two-sided)
# line 2: says if the analysis has been started or not. 0 for not started. 1 for already started.
# line 3: critical values in the scale of Sn
# line 4: observed cases
# line 5: actual alpha spent
# line 6: cumulative expected value of Sn E[sum(w*C)] under H0, test by test
# line 7: has the target alpha spending until the (test-1)th look.
# line 8: observed controls
# line 9: CVl
# line 10: the number of rows (different weights/z ) per test
# line 11: matched case-control
# line 12: PENSAR
# line 13: weight for each observation
# line 14: test per weight
