基于Hyperledger Fabric1.4 自定义搭建自己的区块链（二）
四、generateChannelArtifacts函数
使用configtxgen工具根据configtx.yaml文件来生成创世区块和通道相关信息，更新锚节点。
1、生成启动 Orderer 需要的初始化区块，并支持检查区块内容；
2、生成创建应用通道需要的配置交易，并支持检查交易内容；
3、生成 2 个锚节点 Peer 的更新配置交易。
configtxgen 调用的配置文件为 configtx.yaml ，该配置文件一般包括四个部分：
1、Profiles：一系列通道配置模板，包括 Orderer 系统通道模板和应用通道类型模板；
2、Organization：一系列组织结构定义，被其他部分引用；
3、Orderer：Orderer 系统通道相关配置，包括 Orderer 服务配置和参与 Ordering 服务的可用组织信息；
4、 Application：应用通道相关配置，主要包括参与应用网络的可用组织信息。
调用该函数最终在 channel-artifacts 目录下生成了四个文件，对应于上述的三个功能：
channel.tx genesis.block OrgaMSPanchors.tx OrgbMSPanchors.tx
