Iterator over const VDB primitives on a geometry detail.
At least until GEO_PrimVDB becomes a built-in primitive type (that can be used as the mask for a GA_GBPrimitiveIterator), use this iterator to iterate over all VDB grids belonging to a gdp and, optionally, belonging to a particular group. 
| using FilterFunc = std::function<bool (const GU_PrimVDB&)> | 
| 
 | explicit | 
| gdp | the geometry detail over which to iterate | 
| group | a group in the detail over which to iterate (if nullptr, iterate over all VDB primitives) | 
| filter | an optional function or functor that takes a const reference to a GU_PrimVDB and returns a boolean specifying whether that primitive should be visited ( true) or not (false) |

Allow primitives to be deleted during iteration.
| void advance | ( | ) | 
Advance to the next VDB primitive.

| const GU_PrimVDB * getPrimitive | ( | ) | const | 
Return a pointer to the current VDB primitive (nullptr if at end). 
| UT_String getPrimitiveIndexAndName | ( | bool | keepEmptyName = true | ) | const | 
Return a string of the form "N (NAME)", where N is the current VDB primitive's index and NAME is the value of the primitive's name attribute. 
| keepEmptyName | if the current primitive has no nameattribute or its name is empty, then if this flag istrue, return a string "N ()", otherwise return a string "N" omitting the empty name | 
| UT_String getPrimitiveName | ( | const UT_String & | defaultName = "" | ) | const | 
Return the value of the current VDB primitive's name attribute. 
| defaultName | if the current primitive has no nameattribute or its name is empty, return this name instead | 
| UT_String getPrimitiveNameOrIndex | ( | ) | const | 
Return the value of the current VDB primitive's name attribute or, if the name is empty, the primitive's index (as a UT_String). 
| 
 | inline | 
Return false if there are no more VDB primitives.
