    Description copied from interface: JepComponent
    
    Initialize the component. This methods is called whenever a component is added to Jep. Hence it allows components to keep track of the other components they may rely on.
    
    Specified by:
    
    init in interface JepComponent
    
    Overrides:
    
    init in class VariableTable
    
    Parameters:
    
    j - the current Jep instance
  - newInstance
```
public VariableTable newInstance()
                          throws JepException
```
    Creates a new SymbolTable with the same variable factory as this, and the same set of constants.
    
    Throws:
    
    JepException
  - print
```
public void print(PrintVisitor pv)
```
    Prints the contents of the symbol table displaying its equations and value.
