Detailed Description

Logic output.

Adds to interface:
if width = 1 then
<name> : out std_logic
if width > 1 then
<name> : out std_logic_vector(width-1 downto 0)
where <name> is c++ object name.
Any number of instances are allowed.

// This is an example that show how to use the FC_IO_Out and FC_IO_In classes.
// When x changes the busy signal goes high and the square root is calculated.
// When the result is ready busy goes low.
