2014.11.13
   1. 修正eos2中拉伸失效对压力的处理方法（将压力置零，与MPM3D一致）。原来的处理方式会导致在计算超高速碰撞算例时，
      在计算后期边界附近的粒子速度突然会变得很大。
   2. 增加超高速碰撞算例文件及说明文件：LeadHypervelocityImpact.mpm & 铅球超高速撞击铅靶.pdf

2014.9.9
   1. Bug fix. Line 407 in Constitution.f90:  dinc(2)*(sold(2)+sd(1)) ===> dinc(2)*(sold(2)+sd(2))
   2. Use half step size when updating the velocity at the first time step:  Line 312 in update_step.f90
   3. Line 15 in Taylor.mpm: spz  0.0 26.28 ===> spz  0.0 26.6

2014.6.12
   1. Bug fix. Line 404 in DataIn.f90: mat_list(i)%MatType = 10  ===> mat_list(i)%MatType = 7
2014.4.2
   1. Fix the bug of the frictional force calculation in subroutine Lagr_NodContact()
   2. Adjust the calculation steps: the step 2 is only for USF in program MPM3D
   3. Fix the bug for Cutoff calculation in DataIn module.
   4. Fix the bug for the kinetic energy calculation in  DataIn module
   5. Modify some comments
   
2014.1.24
   1. 增加第251~252页A.2.3节算例的输入文件TNT3D.mpm

2013.12.9
   1. Change the format of POINT keyword to: part point comID num(i);
   2. Change "pmass(r)" in BLOCK and SPHE to "density(r)";

2013.10.9
   Fix bugs caused by uninitialized variables in Class Particle.
