        /* The goal of this option is to ensure that local ordering remains
             * consistent between different iterations of soot. This helps to ensure
             * things like stable string representations of instructions and stable
             * jimple representations of a methods body when soot is used to load
             * the same code in different iterations.
             * 
             * First sorts the locals alphabetically by the string representation of
             * their type. Then if there are two locals with the same type, it uses
             * the only other source of structurally stable information (i.e. the 
             * instructions themselves) to produce an ordering for the locals
             * that remains consistent between different soot instances. It achieves
             * this by determining the position of a local's first occurrence in the 
             * instruction's list of definition statements. This position is then used
             * to sort the locals with the same type in an ascending order. 
             * 
             * The only times that this may not produce a consistent ordering for the 
             * locals between different soot instances is if a local is never defined in
             * the instructions or if the instructions themselves are changed in some way
             * that effects the ordering of the locals. In the first case, if a local is 
             * never defined, the other jimple body phases will remove this local as it is 
             * unused. As such, all we have to do is rerun this LocalNameStandardizer after
             * all other jimple body phases to eliminate any ambiguity introduced by these
             * phases and by the removed unused locals. In the second case, if the instructions
             * themselves changed then the user would have had to intentionally told soot to
             * modify the instructions of the code. Otherwise, the instructions would not have
             * changed because we assume the instructions to always be structurally stable
             * between different instances of soot. As such, in this instance, the user should
             * not be expecting soot to produce the same output as the input and thus the
             * ordering of the locals does not matter.
