Goldstein解缠算法基于二维Goldstein枝切相位进行解缠，输入为.mat格式的复数据，输出为解缠相位图像(GoldsteinUnwrap2D implements 2D Goldstein branch cut phase unwrapping algorithm.
Inputs: 1. Complex image in .mat double format
　2. Binary mask (optional)　　　　　
Outputs: 1. Unwrapped phase image
　　　　　2. Phase quality map
This code can easily be extended for 3D phase unwrapping.
