ASCII Mnemonic Expansion

When dealing with streams of ASCII-encoded data, it is often helpful to be able to see non-printing and white space characters. This is especially useful when logging. The ExpandAscii() extension method makes this simple. Us string.ExpansAscii() and cahacters such as carriage return, for example, will be rendered as \<CR\> instead of causing an ugly line break in your log output.

ExpandAscii() uses the mnemonics defined in the AsciiSymbols enumerated type.
