# Node initialization with default value for drag and drop from socket

## Goals:
Initialization of nodes can be with any data. This ties in well with the drag and drop feature. Some layer of abstraction will unify the creation of a node with known data in advance.

## Plan:

static void node_init(bNodeTree * /*tree*/, bNode *node)
{
  NodeFunctionFloatValue *data = MEM_cnew<NodeFunctionFloatValue>(__func__);
  data.value = 0.0f;
  node->storage = data;
}

can be changed on:

static void node_init(bNodeTree * /*tree*/, bNode *node, NodeValueProvider &provider)
{
  NodeFunctionFloatValue &data = *MEM_cnew<NodeFunctionFloatValue>(__func__);
  data.value = provider.value<float>();
  
  // provider.subtype();
  // provider.type();
  // provider.min();
  // provider.max();
  // ...
  
  // StringRef socket_name = provider.for_socket();
  // if (socket(name) == input, index == 0, type == ...)
  
  node->storage = &data;
}
