\brief String class supporting common string operations.

BString is a string allocation and manipulation class. The object
takes care to allocate and free memory for you, so it will always be
"big enough" to store your strings.

\name Assignment Methods

To assign a string to the object, thus overriding the previous string
that was stored, there are different methods to use. Use one of the
overloaded Adopt() methods to take over data from another object. Use
one of the assignment operators to copy data from another object, or
use one of the SetTo() methods for more advanced copying.

\name Comparison Methods

There are two different comparison methods. First of all there
is the whole range of operators that return a boolean value, secondly
there are methods that return an integer value, both case sensitive
and case insensitive. 

There are also global comparison operators and global compare functions.
You might need these in case you have a sort routine that takes a generic
comparison function, such as BList::SortItems().
See the String.h documentation file to see the specifics, though basically
there are the same as implemented in this class.
