You are given an alignment in ClustalW format. Write a Python program to
convert this to FASTA format and print it to the screen. The ClustalW format
begins with the line "CLUSTAL W (1.83) multiple sequence alignment"  
followed by two blank lines.  Following that the alignment begins with the
sequence name followed by spaces and the sequence on separate lines.
However, the alignment is broken by sequence length into chunks of 60
characters. Below is an example of a ClustalW alignment.
