floor block length

[micahwoodard]

Floor block length to match current implementation. Updates curriculum to increase upper bound since max is exclusive. resolves #116

[micahwoodard]

Replicated the current code base rounding pattern

if self.TP_Randomness == "Exponential":
            self.BlockLen = np.array(
                int(
                    np.random.exponential(float(self.TP_BlockBeta))
                    + float(self.TP_BlockMin)
                )
            )
elif self.TP_Randomness == "Even":
            self.BlockLen = np.array(
                np.random.randint(
                    float(self.TP_BlockMin), float(self.TP_BlockMax) + 1
                )
            )
