String Buffer: Manipulate text strings as with Java StringBuffer

This class is meant to access and manipulate text string objects as with Java StringBuffer class and the Enumeration interface.

It provides extensive support for string manipulation as well as having built-in enumeration that allows input parameters ranges to be taken care of. The advantage of this for the programmer is that it cuts down iteration code needed to be written.

It also provides string manipulation functions to delete characters and to insert a string in another string.
