Detailed Description

A bit-field class for identifying logger message types.

For now, you can specify message "level" (e.g. Warning versus Debug messages) flags and message "source" (where a message originates) flags. These flag sets occupy exclusive portions of the bit-field, so they are combined using the bitwise-and operator (&). Flags from the same set can be combined using the bitwise-or operator (|). For example, here is one correct (if verbose) way to specify a mask for all messages from the container framework:

LoggerLevel l = CONTAINERS & ALL_LEVELS;

or, if you wanted to capture warning or error messages from everything:

LoggerLevel l = (ERROR | WARNING) & ALL_SOURCES;

Of course, in these cases, it would be sufficient to omit the ALL_LEVELS and ALL_SOURCES flags, because these are implicit -- all of the message level flags imply an acceptance of all sources, and vice-versa. A more complicated example might look like this:

LoggerLevel l = (ERROR | WARNING) & (ATOMS | CONTAINERS);

which would accept all error and warning messages from the atom and container frameworks.
