Big Update

-Changed maxperiodlist function to loop over t_max/T instead of range(t_max)
-Got rid of figure 2 and 3 (and all formatting that came with them), all information is now condensed into graphs on figure 1
-Figure 1 now has a graph that shows 1) fraction of transits detected 2) geometric probability of spotting a transit and 3) the product of the two
-overall_period now returns a list of fractions to multiply by the geometric probability and get a total probability of missing a transit
