> BasePage.fetchFieldFromSlot needs to construct a FetchDescriptor with single column.
To do this it creates a FormatableBitSet that identifies the correct column and then passes
this bitset to the FetchDescriptor constructor. But FetchDescriptor has a special constructor
for the single column case, that doesn't need a bitset. Using this constructor instead makes
the code simpler, and presumably more efficient as well.
