+This class will help compute IMAGE_FSTYPE dependencies and group them in batches
+that can be executed in parallel.
+
+The next example is for illustration purposes, highly unlikely to happen in real life.
+It's just one of the test cases I used to test the algorithm:
+
+For:
+IMAGE_FSTYPES = "i1 i2 i3 i4 i5"
+IMAGE_TYPEDEP_i4 = "i2"
+IMAGE_TYPEDEP_i5 = "i6 i4"
+IMAGE_TYPEDEP_i6 = "i7"
+IMAGE_TYPEDEP_i7 = "i2"
+
+We get the following list of batches that can be executed in parallel, having the
+dependencies satisfied:
