OVX-Java仿真 v2.0 版本
版本说明：
v2.0: Final completed version.
1.2-as-dep version: Can be use as dependency allocation computer.
1.2版本拟增加回溯，优化方法调用。
1.1版本每次运行可进行多次资源映射。
1.0版本每次运行只能运行一次映射，下一个版本将增加多次映射功能。
## 1. 运行环境
- 系统环境：Windows / Linux
- 软件环境：Java-1.8 version
- 编译依赖：Maven
## 2. 运行方法
编译方法：
```
mvn clean install
```
运行示例：
```
java -jar ovx-simulation-jar-with-dependencies.jar
