	\ingroup libbe
	\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.

	While BString is in essence a wrapper around a byte-array, which can always
	be accessed with the BString::String() method, it does have some
	understanding of UTF-8 and it can be used for the manipulation of UTF-8
	strings. For all operations that perform on bytes, there is an equivalent
	that operates on UTF-8 strings. See for example the BString::CopyInto() and
	BString::CopyCharsInto() methods. The main difference is that if there are
	any position argumens, the regular method counts the bytes and the
	Chars methods counts characters.

	If \a maxLength is greater than the length of the source \a string then the
	entire source \a string is copied. If \a maxLength is less than or equal

	\name Comparison

	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
