AML syntax versus pythonic syntax

This is a simple example to illustrate that the old AML syntax can still be used, as well as the new object-python syntax

meri1 = Histogram("../../test/data/meri1.his")
meri2 = Histogram("../../test/data/meri2.his")
meri3 = Histogram("../../test/data/meri3.his")
meri4 = Histogram("../../test/data/meri4.his")
meri5 = Histogram("../../test/data/meri5.his")

#Merge the histograms
meri_a = Merge(meri1, meri2, meri3, meri4, meri5)
print meri_a.display()

meri_b = meri1.merge([meri2, meri3, meri4, meri5])
print meri_b.display()

The two Merge calls return the same output:
