+// if a plane cut intercepts of lengths l1,l2,l3 the on three crystal axes ,then

+// l1 : l2 : l3 = pa : pq :rc

+// where a,b and c are primitive vectors of the unit cell and p,q and r are numbers related to miller indices (hkl) of plane by relation

+// 1/p : 1/q : 1/r = h : k : l

+//since, the crystal is simple cubic a = b = c and given that h = 1, k = 1 and l = 1

+// p : q : r = 1/h : 1/k : 1/l = 1/1 : 1/1 : 1/1 

+// p : q : r = 1 : 1 : 1

+//similarly l1 : l2 : l3 = 1a : 1a : 1a
