Norm

Summary:
The Norm function removes leading zeros or ones from the input, X, to form the mantissa, 
Z, and exponent, E.  E indicates the number of leading 0's or 1's that were removed 
from the input.  If the input is zero, then E will have its maximum value. The width 
of X and Z is controlled by Width.  The width of E is chosen automatically
to allow full normalization of X. The logic is always optimized for minimum possible
delay.

Function: 
    Z=mantissa(X)
    E=exp(X)

Signals:
    Z: Width wide mantissa output
    E: exponent output (width chosen automatically=ceil(log2(width(X))))
    X: Width wide input

Parameters:
    Name: actual module name
    Width: width of the X and Z signals
    LeadingO: remove leading zeros when selected, remove leading ones otherwise

Verilog Usage:  
    Name(X,E,Z);
