Reads data from file and writes the projections onto the largest
<font color=blue><tt>m</tt></font> principal components as columns.
Output file <font color=blue><em>file</em><tt>_pc</tt></font>.
For each principal component, the fraction of the variance (not rms amplitude)
covered and the accumulative fraction of the variance covered keeping all
components so far 
are printed on <font color=blue><tt>stderr</tt></font>.
