add CreateChildrenAsync & update abp v3.5

var beijing = new Region
{
	Name = "beijing"
};
await _generalRegionTreeManager.CreateAsync(beijing);

var xicheng = new Region
{
	Name = "xicheng",
	ParentId = beijing.Id
};

var dongcheng = new Region
{
	Name = "dongcheng",
	ParentId = beijing.Id
};

await _generalRegionTreeManager.CreateChildrenAsync(beijing, new List<Region>
{
	xicheng,
	dongcheng
});

GeneralTree update & move methods to increase the processing of sub-items.

await _generalTreeManager.UpdateAsync(tree, x => 
{
	x.MyCustomData = x.Code; 
});

await _generalRegionTreeManager.MoveAsync(tree.Id, newTree.Id, x =>
{
	x.MyCustomData = x.Code; 
});

add IGeneralTreeDto ToTree Extensions

public interface IGeneralTreeDto<TTree, TPrimaryKey> : IEntityDto<TPrimaryKey>
	where TPrimaryKey : struct
{
	TPrimaryKey? ParentId { get; set; }

	ICollection<TTree> Children { get; set; }
}

Support for children ToTree.

Add an extension to transform a collection into a tree entity

public void ToTree_Test()
{
	var regions = new List<Regin>
	{

	};

	var tree = regions.ToTree<Regin, long>().ToList();

	tree.ShouldNotBeNull();
	tree.Count.ShouldBe(2);
	tree.First().Children.Count.ShouldBe(2);
	tree.Last().Children.Count.ShouldBe(2);
	tree.Last().Children.Last().Children.Count.ShouldBe(1);

Public Fill Up Tree method

• Public Fill Up Tree method
  For the convenience of some people want to use third-party libraries.
  such as: http://entityframework-extensions.net/overview
• Update abp to v3.3.0

Compatible with low version of abp(2.3.0)

Compatible with low version of abp(2.3.0)

FullName support custom Hyphen.

FullName support custom Hyphen.

public GeneralTreeConfiguration()

	Hyphen = "-";
}

ExceptionMessageFactory

Support for custom exception message: ExceptionMessageFactory

public GeneralTreeConfiguration()

BulkCreateAsync

We need BulkCreateAsync to solve the performance issue of bulk additions.
