#  Parameters - Class for sharing data between classes
## Using
* Copy the source files into the corresponding directory in your project
* Create a pointer and initialize the class. For example:

```
Parameters *parameters = Parameters::GetInstance();
```

It's the only way to initialize it, because the constructor is private.

## How it works?
On the first initialization, it reads the file in the given format:

Energy Shape <br />
Length_X Lenght_Y Length_Z <br />
Nx Ny Nz <br />
index material (*Nx*Ny*Nz)


Throws error if the index is incorrect in the file.

## Public functions

Returns with the material form the list by it's index (returns -1 if the index is out of range): 

```
double GetMaterial(int index);
```

Returns with the material from the list by it's coordinates (not implemented yet):

```
double GetMaterial(int x, int y, int z);
```

Returns with the list size:

```
double GetListSize();
```

Returns with the vector:

```
std::vector<double> GetMaterialList();
```
