…nd re-execute "back()" let multiple functions additionally know if user requested derivative generation
…uested by the user added function to split the algebra product "first * second" into two independet instances for derivative generation, i.e. "back()" will be executed twice, resulting in multiple .hh and .cc files
different code generation for first and second derivative in "inject_derivative_body" and "init_derivative_recording" added new function "derivative_collect_traces" replace bool "inject_derivatives" with int "ast.current_derivative" "push_back_ret_decl" also declares variables "edgeweight" to record these in addition to vdot
…uested derivative generation made "class_name" private to enforce use of convenience functions "set_class_name" and "get_class_name_lower_derivative" to prepend "_derivativeX" if necessary
…at unused variable does NOT get generated

gapc will produce the following files, if you ask for second derivatives
--derivative 2. You also have to specify an algebra product likeleft * rightwhere left and right algebras must be synoptic!adding additional member q, since D2 needs to store both vdot and q for candidates (note that naming schema is messed up!)
