## Updates
* 2020/02/06 - SiPMAnalisys' and SiPMParameters' GetInstance functions are returning a static reference instead of pointer
* 2020/02/06 - G4Mutex replaced with std::mutex
* 2020/02/06 - Input config file and output data file name can be changed with the GetInstance functions on the first call
## Running
Run with default parameters (not always works)
```
./sipm
```
Run with default config file (config.conf)
```
./sipm -df
```
Run with custom config file
```
./sipm -f config_file_name.conf
```
## Config file parameters

* sipmsizex - SiPM X Size
* sipmsizey - SiPM Y Size
* sipmsizez - SiPM Z Size
* scintillatorsizex - Scintillator X Size
* scintillatorsizey - Scintillator Y Size
* scintillatorlength - Scintillator Z Size
* scintillatorisbox - Scintillator can be a tube or a box
* coatingthickness - Scintillator coating thickness
* scintillatorradius - Radius of the scintillator. Only used when it is a tube.
* xdivision - How many detectors should be placed along the X axis
* ydivision - How many detectors should be placed along the Y axis
* pgenergy - Particle Gun energy
* numberofevents - Number of events
* lengthunit - Size unit in detector construction (mm | cm | m)
