[boost] [MultiIndex] proposal - delayed index initialisation and maintenance

I am just sort of throwing this out there as a wild idea.

Having a trait on any given index such that it is
only initialised upon first access.

The motivation being - When displaying a table of rows
of fields, the user may not
necessarily click on any given column header
for sorting, and would only rarely click on
the majority of column headers. Therefore it
is not required to maintain any given
column index unless the user has requested
sorting by that index.
