public static int getExpressionLocByLocation(String loc,
                                             Stack expression)
                                      throws FormulaNotFoundException
```
    returns the position in the expression stack for the ptg associated with this location
    
    Parameters:
    
    loc - String
    
    expression -
    
    Returns:
    
    Throws:

  - getExpressionLocByPtg
```
public static int getExpressionLocByPtg(Ptg ptg,
                                        Stack expression)
                                 throws FormulaNotFoundException
```
    returns the position in the expression stack for the desired ptg
    
    Parameters:
    
    ptg - Ptg to lookk up
    
    expression -
    
    Returns:
    
    Throws:
    
    FormulaNotFoundException
  - getCellRangePtgs
```
public static Ptg[] getCellRangePtgs(Stack expression)
                              throws FormulaNotFoundException
```
    getCellRangePtgs handles locating which cells are refereced in an expression stack. Essentially the use is we can check a formula if it refereces a cell that is moving, then we have the ability to manipulate these ranges in whatever way makes sense.
    
    Returns:
    
    an array of ptgs that are location based (ptgRef, PtgArea)
    
    Throws:
    
    FormulaNotFoundException
