示例1: setAttribute
/**
* @brief Update attributes WorkspaceIndex and Q according to certain precedence
*rules.
* Subclasses featuring additional attributes should override and insert a call
*to
* this method within the overriding setAttribute function.
* There are two ways to update Q: (i) loading the value from the spectrum, and
*(ii) manual
* input from the user. Therefore, rules of precedence must be set to prevent
*conflict. The
* priority is to accept Q from the spectrum, if a Q value can be derived from
*such. In
* this case the existing Q value will be overwritten, irrespective of the
*mannier in which
* the old Q value was set.
*
* @param attName name of the attribute
* @param attValue value of the attribute
