IMO, a _nested_ struct/class should have visibility (and access permission(?)) into the nesting class, but it doesn't (except, rather oddly, for the static consts of MSAsRaster: TIME, NAXES, etc., which are directly in scope and accessible here).
Hence the need to have a pointer to the nesting object and for it to declare this class a friend. The nesting class's 'this' should be available implicitly to this class instead. As is, it's rather clumsy to implement classes/structs that are purely in support of another class...\.

An MSpos_ holds information about a given position of interest within the main MS visibility Table.
Its data members are the values at that position as actually stored in the MS (times, antennas, etc.); these can be freely set and queried by MSAsRaster, the only user of this struct. It provides translation between these values and the hypercube indices (pos_) used internally. It was time to quit performing these translations ad hoc and consolidate them here (3/04). (Still to do: use this instead of old ad hoc methods in, e.g., showPosition()).
When MS selection changes, MSAsRaster::findRanges_() computes several tables (time_, spwId_, freq_, polId_, nAnt_, etc.) which [re-]define the correspondence of MS data to hypercube positions. An MSpos_ set up prior to this change can be queried afterward as to the data's position (if any) in the new hypercube. It is also useful in determining whether flagging edits (which are stored in terms of hypercube positions) apply to MS data beyond what is currently selected.
Below is the real content of an MSpos_: data for a position within an MS in terms of the values actually stored there. Note that, in its current version, MSAsRaster assumes that this data uniquely determines a visibility-and-flag within the MS (and feed is not considered either, when there is more than one antenna).
