docs: Checking a method if it is reflective executable and if the mapping to the object fits.
  
  @param obj   on which the execution takes place
  @param anno  the related annotation for the check
  @param meths to be checked
  @return {@link PerfidixMethodCheckException} if something is wrong in the mapping, null otherwise.
