This class defines a member specification within a DeepSee query.
A member specification defines a specific member from a dimension
such as "[Product]", "[Product].[Name]", or "[Location}.[Boston]".
A set of members may be grouped within a single tuple or a single member
may exist stand-alone.
Every memberSpec has a corresponding member object
that implements any operations needed to be run against the member,
such as getting a list of dimension members for a given member.

method %PreProcess(pIsSlicer As %Boolean = 0)
