 In this example, a powder pattern is used to solve the crystal
 structure of Cimetidine. This covers all the steps: loading the
 data, indexing the pattern (determining the unit cell), finding
 the spacegroup, profile fitting, and solving the structure
 using a global optimisation algorithm.

+In this example, two powder patterns (X-ray and neutron) are used to solve
+the crystal structure of PbSO4. This covers all the steps: loading the
+data, indexing the pattern (determining the unit cell), finding
+the spacegroup, profile fitting for the two patterns, and solving the
+structure using a global optimisation algorithm.
