+TetraGM4.0 四面体网络正演程序
+2015/11/12
+    为避免之前版本中的冗余计算过程，在4.0版本中我们将对程序的数据结构做出调整（大改）。
+通过模型对比实验，程序的计算效率有了质的提升。同时4.0版本更适合与并行计算的要求。调整后
+的程序结构任未达到最优化状态，但进一步的优化需要获取更多的网络信息（每一条边的索引、每
+一个面的索引）。准备从其他格式的网络文件（如.msh文件）中寻找突破口。
+2015/11/13
+    今天在程序中加入了并行执行的命令，程序的运行效率有了进一步的提升。在i5，4G内存平台上
+提升率约为原计算效率的两倍。相信在更高主频的平台能取得更好的成绩。
+
+程序数据结构：调整后基本数据结构如下。
+			  point3d（矢量结构）：矢量的坐标（x,y,z）
+			  sphere_point（球面点/地理坐标系）：顶点的经纬值与球坐标半径
+			  vertex（顶点结构）：顶点的索引号，点坐标
+			  edge（边结构体）：边的编号，边的顶点索引，边的属性，边的长度，边的张量积E
+			  face（面结构体）：面的编号，面的顶点索引，面的属性，面的张量积F
+			  tetra（四面体结构体）：四面体的索引号、
+			                         四面体四个顶点的索引号、
+									 重新排序后的四组三角形的索引号（记录排序后信息有利于后续的利用，避免函数的重复调用）
+			                         四个面的张量积F、
+									 六条边的张量积E与边的长度（F、E与边长四面体是的固有属性，首先计算出来可以有效减少冗余计算）
+									 四面体属性值
+程序文件结构：Data_Func.h文件定义了数据类型与需要使用到的矢量运算函数
+              Commond_Line.h文件定义了程序中规定的命令行操作符
+			  res_reg.h文件定义了计算结果的暂存与写入文件函数
+			  Tetra_G.h文件定义了重力场正演类
+			  Tetra_M.h文件定义了磁场正演类
+			  main.cpp识别命令行指令，调取相应函数响应
