POWER implements power operator for analysis objects.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: POWER implements power operator for analysis objects.
computes b.^c where b is an analysis object and c is
either another analysis object or a constant.
CALL: a = a1.^scalar

The following call returns a parameter list object that contains the
default parameter values:
>> pl = power(ao, 'Params')
The following call returns a string that contains the routine CVS version:
>> version = power(ao,'Version')
The following call returns a string that contains the routine category:
>> category = power(ao,'Category')
