Add documentation for the I_ACCESS_LIST new parameter extracted and added to instrumentation line

[MichaelOsorio2017]

Recently I found that the compiler sometimes generates bridge and synthetic methods See link for more info, some of them have the same name than the original one and the last used conditionals weren't good enough identifying these two different methods. The I_ACCESS_LIST allows the differentiation among them

Example:

• Original method:
  
  I_ACCESS_LIST values for this method: public
• bridge and synthetic compiler generated method:
  

I_ACCESS_LIST values for this method: public bridge synthetic

With this change the tool is able to differentiate and instrument the right method without generating problems in the smali files.

This new change is highly related to the issue #8 it may start decreasing the list mentioned in that issue
