//      isInteger(String)           Returns true is the string is an integer
//      isNumeric(String)           Returns true is the string is a number

//      DecodeDelimittedList(List, Delimitter)  
//          Returns an array where each entry is a list item. The specified list
//          specifies entries seperated by the delimitter character.

//      siif(Condition, If True, If False)
//          Performs an inline test of som condition, returning the If True expression
//          if the condition true, and If False otherwise.  Both If True and If False
//          must evalauate to valid expressions regardless of the condition.

//      HideElement(Control ID)   Makes the specified control invisible. The element is returned.
//      ShowElement(Control ID)   Makes the specified control visible. The element is returned.

//      PlaceElement(Control ID, Top, Left)
//          Shows the specified control at the specified coordinates. Returns the control.

//      AddElement(Parent, Tag, ID)
//          Returns a new HTML element given by the Tag.  Both the NAME and ID 
//          properties are set to the specified ID.  If the Parent exists,
//          the new control is added to the parent's list of controls.

//      RemoveElement(Control ID)
//          Removes the specified control from its parent.  The control is returned.

//      SwapElement(Control ID, New Parent ID, Show Flag)
//          Removes the specified control from its parent, and assigns the control
//          to the New Parent's list of controls.  If the Show Flag is true, the
//          control will be displayed.  The control is returned.

//      SetClassName(Control ID, Class Name)
//          Sets the specified control's CLASS property to the specified class name.
//          The control is returned.

//       SetBrowserClassName(Control ID, ClassName) 
//          Sets the CLASS property of the specified control based the current browser
//          environment IE vs FireFox.  Class names beginning with "IE" indicate Internet
//          Explorer classes, where "FF" indicates FireFox classes.  The control is returned.

//      FormatCurrency(Number, Include Cents)
//          Returns a formatted currency string based on the number, including cents
//          if the Include Cents flag is set to true.

//      Dice(Sides, Number)
//          Returns an integer represting die of the specified sides thrown the
//          specified number of times.

//      Wait(Milleseconds)
//          Pauses script execution for the specified number of milleseconds.

//      IndexOf(Value, Array) 
//          Returns the index of the first occurrence of the specified value
//          within some array.  If the value is not found, the function returns -1.

//      Thousands(Number)
//          Returns a string based on some number in comma-seperated format: ...#,###,##0

//      ZeroStr(Number, Length)   
//          Returns the stringer version of some number, padded to the left with zeros,
//          and cut to the specified length.

//      IsOdd(Number)          Returns true of the number is odd, otherwise false (even).

//      SetBackgroundImage(Control ID, Image SRC URL)
//          Sets the background image of the specified control to some URL.
//          The control is returned.

//      SetSpanString(Control ID, Text)
//          Sets the InnerHTML property of the specified control. The control is returned.


//      SetSelectedIndex(Control ID, Index)
//          Sets the SelectedIndex property of the specified control.  The control is returned.

//      FindByID(ID, Array of Objects)
//          Returns the index of the first occurrence of the ID within an array of objects.
//          Each object in the array must possess a property named "iID", a common method
//          of indexing objects in memory.  If the object is not found, the function returns -1.

//      IsEMailValid(EMail) 
//          Returns true if the e-mail address is valid, otherwise false.

//      StrToHex(Integer)       Returns the hexedecimal version of the specified integer.
