Detailed Description

OD::String with its own variable length buffer. The buffer has a guaranteed minimum size.

The minimum buffer size makes life easier in worlds where strcpy etc. rule. Overhead is 4 extra bytes for variable length and 4 bytes for minimum length.

Constructing/asigning/comparing etc. with a (char*) null pointer is no problem.

Don't try to add constructors with a single basic type - this leads to nasty hidden bugs because the compiler will try to convert all kinds of things into BufferStrings. If you just need a string from an int, float, ..., just use str = toString( var ). If you need the BufferString later, use:

BufferString istr( "", intvar );
