fengjiayi 48289dae11 1. 修改了FlowResult的创建方式,新增了IsSuccess与Message,为后续进行流程日志追踪准备。
2. 修复了删除节点时,没有正确消除与之相关的参数获取关系。
3. IFlowNode新增了StartFlowAsync方法。
4. Library项目中FlowNodeExtension拓展类转移到了NodeFlow项目中。
5.  修改了Script自定义参数保存,对参数类型、返回值类型进行保存。
6. Library.Utils.BenchmarkHelpter中添加了Task、Task<>的重载方法。
7. NodeFlow项目中,FlowEnvironment默认使用通过NewtonsoftJson实现的JSON门户类。
8. NodeFlow项目中,FlowControl缓存了 FlowWorkOptions 选项实体,并且对于 FlowWorkManagement 进行了池化管理(但后续的项目中考虑重构流程任务运行时)。
