This PlugIn computes strain tensors based on the least square method.
This method is based on this paper [1]. Note that this plugin is applied 
on `DEM::Element` with `DEM::Strain` property. If the `DEM::Strain` does 
not exist, it is automatically created. 
 
### Info ###
+ Process on         : `DEM::Element` with `DEM::Strain` property
+ Multithreaded      : No
+ Recommended section: Processing 
 
### Required param ###
Method (string)
:    The name of the method for computng the strain. 
     Actually, only the 'LSQ' method (least square)  
     is available
 
### Optional param ###
Periodic (boolean, default=False)
:   If you use periodic boundaries, you must activate this flag
 
IgnoreDisableBond (boolean, default=True)
:   If set to true, the plugin will ignore the disabled bond from the strain calculation
 
### Example ###
```
 <UPDATE-STRAIN Method="LSQ" />
```
 
### Simulation example ###
`00012_{lattice}{dem}{mechanical}{elastic}{flatbond}_TENSILE-TEST` and all the flat bond examples
