% DESCRIPTION: LOG10 overloads the log10 operator for analysis objects.
%              Common (base 10) logarithm.
%              LOG10(ao) is the base 10 logarithm of the elements of ao.data.
%
% CALL:        ao_out = log10(ao_in);
%              ao_out = log10(ao_in, pl);
%              ao_out = log10(ao1, pl1, ao_vector, ao_matrix, pl2);
