Similar to other Dune modules

The files were for compatibility only. They are
superseded by files created for any Dune module.

Delete parallel/.

Couple of links, only for backwards compatiblity with ug 3.13

Remove unused subfolder dom/gen/ and its content.

But it remains meaningless

Merge branch 'get-rid-of-uggrid-heapsize' into 'master'

See merge request [!142]

  [!142]: Nonestaging/dune-uggrid/merge_requests/142

This option used to be the heap size, but ever since we started
using the system heap for everything that size does not get
used anymore.

It is not used anyway.

Merge branch 'fix_warnings_unused_function' into 'master'

ref:staging/dune-uggrid Added preprocessor if-conditions and commented out
some unused functions to avoid compiler warnings made by CI test
"gcc-7-14-sequential".

See merge request [!127]

Deleted the function "CheckNodeContext" because it was not used in.
````
static INT CheckNodeContext (ELEMENT *theElement, NODE ** NodeContext)
{
  INT i, mark,nor,noc;

  mark = MARK(theElement);
  for (i=CORNERS_OF_ELEM(theElement); i<CORNERS_OF_ELEM(theElement)+EDGES_OF_ELEM(th       eElement); i++)
  {
    if (NODE_OF_RULE(theElement,mark,i-CORNERS_OF_ELEM(theElement))) nor = 1;
    else nor = 0;
    if(NodeContext[i]!=NULL) noc = 1;
    else noc = 0;
    if(nor!=noc)
      if (GetNodeContext(theElement,NodeContext)) REP_ERR_RETURN(1);
  }
  for (; i<CORNERS_OF_ELEM(theElement)+EDGES_OF_ELEM(theElement)+SIDES_OF_ELEM(theEl       ement); i++)
    if (NodeContext[i]!=NULL)
      if (GetNodeContext(theElement,NodeContext)) REP_ERR_RETURN(1);

  return (0);
}
````

Deleted the definition of "CheckLocalElementKeys" for the case
````
!(MGIO_DEBUG>0)
````
because all uses in this file are contained in a preprocessor if condtion ensuring
that
````
MGIO>0
````

The function was not needed.

Added a preprocessor if condition around the definition of
"Write_RefRules" because it is used in such an environment.
````
static INT Write_RefRules (MULTIGRID *theMG, INT *RefRuleOffset, INT MarkKey)
{
  ...
}
````

Furthermore there is a comment adressing the only use of "Write_RefRules".

````
/* TODO (HRR 971209): drop old call of Write_RefRules */
  #if EXTRACT_RULES
if (NEW_Write_RefRules(theMG,rr_rule_offsets,MarkKey,&rr_rules)) REP_ERR_RETURN(1)       ;
      #else
if (Write_RefRules(theMG,rr_rule_offsets,MarkKey)) REP_ERR_RETURN(1);
      #endif
````
But i am not sure whether "Write_RefRules" is still needed.

Added a preprocessor if conditon around the definition of "FillSonPaths"
because the only use in this file is contained in such an if condition.
````
 #ifdef __THREEDIM__
static void FillSonPaths (MGIO_RR_RULE *rule)
{

 ...

}
 #endif
````

````
        #ifdef __THREEDIM__
  /* 2D: not even in rm */
  /* son path */
  FillSonPaths(mr);
        #endif
````

I added a preprocessor if-condition to the definition of "RuleCompare"
because the only use in "gm/er.cc" is contained in such an environment in line 698

````
 #ifdef __DEBUG_ER__
static INT RuleCompare (int id, const URULE *ur, const ERULE *er)
{
  ...
}
 #endif
````

````
        #ifdef __DEBUG_ER__
  ...
  RuleCompare(ID(elem),ur,er);
  ...
        #endif
````

I added a preprocessor environment to contain the definiton of the
function: "CheckElementContextConsistency"

````
 #ifdef Debug
static void CheckElementContextConsistency( arguments )
{

 ...

}
 #endif
````
because the following use of the function is also contained in such an
environment.

Merge branch 'fix-vector-leaf-index' into 'master'

ref:staging/dune-uggrid The 'skip' data member of the Vector class used to be
abused for the leaf index of the vector, if that vector corresponds to an
element facet in 3d. By accident, that 'skip' field got removed in a recent
commit. Let's put it back in, but rename it to 'leafIndex' now. All it is used
for nowadays is that leaf index.

Merge branch 'master' into 'master'

ref:staging/dune-uggrid Removed vector::skip and the code that uses it. It
compiles and the few existing tests run without problems.

Fixes [#29]

Closes #29

Henrik Stolzmann authored 5 years ago and Oliver Sander committed 5 years ago

See Issue `#29`.
Removed `vector::skip` and the  code that uses it. It compiles and the
few existing tests run without problems.

Avoid GCC 9 warning

Merge branch 'issue/unused_macros_dim_max' into 'master'

ref:staging/dune-uggrid The macros DIM_MAX and DIM_OF_BND_MAX are not used
anywhere and the DIM_MAX macro conflicts with macros from other libraries. So
they are simply removed. The corresponding `#undef DIM_MAX` should be removed
from dune-grid.
