Description:

This class defines "escape sequences" that influence the formatting of log output. Specific implementations of class Logger have to convert or interpret this classes definitions of escape sequences when processing log data. If no formatting of the output is supported by a specific Logger implementation, such logger should filter and discard escape sequences defined here.

The sequences are similar to ANSI Escape sequences and logger classes that log to 'VT100' compatible terminals will simply convert them.

The name of the class was intentionally chosen to be short, because the escape codes defined with this class will be concatenated to log strings like that:

Log_Info( "The result is: ", ESC::RED, 42 )

Note: With the introduction of own, ALox specific escape codes, software that uses ALox becomes independent of any underlying, platform-specific sequences. For example, ALox is not relying on ANSI color codes, which are not supported by colorful Windows consoles. Instead, on each platform, dedicated Loggers will perform the translation of ALox codes to platform-specific ones.
