  /**
      closeTo(aValue, aDelta) -
      Matches if object is a number close to a given value, within a given delta.
      
      @param aValue   The @c double value to compare against as the expected value.
      @param aDelta   The @c double maximum delta between the values for which the numbers are considered close.
      
      This matcher invokes @c -doubleValue on the evaluated object to get its value as a @c double.
      The result is compared against @a aValue to see if the difference is within a positive @a aDelta.
      
      Example:
      @li @ref closeTo(3.0, 0.25)
  
      (In the event of a name clash, don't \#define @c HC_SHORTHAND and use the synonym
      @c HC_closeTo instead.)
