Loads the change method signature participants for the given element.
Params:
status – a refactoring status to report status if problems occurred while
 loading the participants
processor – the processor that will own the participants
method – the method to be changed
arguments – the change method signature arguments describing the change
filter – a participant filter to exclude certain participants, or null
 if no filtering is desired
affectedNatures – an array of project natures affected by the refactoring
shared – a list of shared participants
Returns:
an array of change method signature participants/**
