Add constructor of class TransformParam

[danlooo]

In order to call function doTransform, an object of type TransformParam must be created. This failes, because the constructor is missing and was not generated by wrapit:

julia> p = Main.DGGRID_jll.DgParamList()
Main.DGGRID_jll.DgParamListAllocated(Ptr{Nothing} @0x00000000029f20f0)

julia> Main.DGGRID_jll.TransformParam(p)
ERROR: MethodError: no constructors have been defined for Main.DGGRID_jll.TransformParam
Stacktrace:
 [1] top-level scope
   @ REPL[35]:1

❯ cat jlDGGRID.cxx | grep constructor
  t1.constructor<DgParamList &>();
  t3.constructor<DgParamList &>();
  t4.constructor<DgParamList &>();
  t5.constructor<DgParamList &>();
  t6.constructor<DgParamList &>();
  t2.constructor<>();

Its there but called auto t6:

  DEBUG_MSG("Adding wrapper for void TransformParam::TransformParam(DgParamList &) (" __HERE__ ")");
  // defined in DGGRID/src/apps/dggrid/dggrid.h:336:7
  t6.constructor<DgParamList &>();

  // defined in DGGRID/src/apps/dggrid/dggrid.h:332:7
  auto t6 = types.add_type<TransformParam>("TransformParam", jlcxx::julia_base_type<MainParam>());

This constructor works in Julia, because it does expect no argument:

julia> Main.DGGRID_jll.DgGridPList()
Main.DGGRID_jll.DgGridPListAllocated(Ptr{Nothing} @0x0000000003352770)

class DgGridPList : public DgParamList {

   public:

      DgGridPList (void);

TransformParam is being constructed using an DgParamList

class TransformParam : public MainParam {

   public:

      TransformParam (DgParamList& plist);

TransformParam::TransformParam (DgParamList& plist)
      : MainParam(plist), inSeqNum (0), outSeqNum (false), inputDelimiter (' '),
        outputDelimiter (' '), nDensify (1)

Adding DgLIntParam.h to input of the wrapit config returns in lots of ambigious binding definition. Maybe due to templates, see https://github.com/grasph/wrapit/issues/5. One can remove duplictaed lines in the generated cxx file resulting in another error:

/workspace/srcdir/dggrid-julia/src/jlDGGRID.cxx:23:42: error: type/value mismatch at argument 1 in template parameter list for ‘template<class T> struct jlcxx::SuperType’
   23 |   template<> struct SuperType<DgParameter> { typedef DgAssoc type; };
      |                                          ^
/workspace/srcdir/dggrid-julia/src/jlDGGRID.cxx:23:42: note:   expected a type, got ‘DgParameter’

Another way is to utilize a veto header for wrapit, e.g. with regex /DgDoubleParam/;. However, this regex will remove all bindings and not just duplicates.

Error of wrong type:

/workspace/srcdir/dggrid-julia/src/jlDGGRID.cxx:195:88: error: no match for ‘operator=’ (operand types are ‘std::vector<DgAssoc*>’ and ‘int’)

Wrapit assumed int but DgAssoc is an empty class:

DgAssoc::~DgAssoc (void)
{
   // does nothing

} // DgAssoc::~DgAssoc
