Boolean operations

Below are the standard operators for managing Booleans:

AND	performs a Boolean AND
OR	performs a Boolean OR
XOR	performs an exclusive OR
NOT	performs a Boolean negation of its input
QOR	qualified OR
S	force a Boolean output to TRUE
R	force a Boolean output to FALSE

Below are the available blocks for managing Boolean signals:

RS	reset dominant bistable
SR	set dominant bistable
R_TRIG	rising pulse detection
F_TRIG	falling pulse detection
SEMA	semaphore
FLIPFLOP	flipflop^bistable
