Release 0.9 introduces a new function h.default that 
simplifies the calculation of the bandwidth parameter
"h" in the functions: fregre.np, fregre.np.cv and fregre.plm.  
In most of the functions has added a stop control when the
dataset has missing data (NA's). It adds the attribute "call"
to the distance  matrix calculated in metric.lp, 
semimetric.basis  and semimetric.NPFDA functions.
