LZ

Summary:
The LZ function counts leading zeros or ones from the input, X, to form the exponent, E.  
The LSB's of E indicates the number of leading 0's or 1's, while the MSB indicates that X is all zeros or ones. 

LZ uses a very fast archictecture (compared to Norm).  It does not normalize the input
as Norm does.

Function: 
    E[n-2:0]=exp(X)
	E[n-1]=X is all zeros or ones, depending on Leading0

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

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

Verilog Usage:  
    Name(X,E);
