CRegisterTable

This class manages register breakdown tables for the Goldenseal estimating software,
small business management software, construction project management software and
construction estimating software.

a breakdown table is used for register view. It shows one object per row rather
than one breakdown entry.

We have not yet figured out an effective way to show registers within
our current editor windows, so this class is not yet used. The problem
is that most objects have more data than can fit in a single data row.
We'll either have to use a "mini-layout" format (and not use a table at
all for the register view), or else allow data for one object to appear
on more than one row (which makes row titling weird).

We also can't use the same table-in-layout format as we do in regular
breakdown tables, since that results in a second scrolling control which
is not very intuitive (what does the "outer" control do then?).

Many users request registers but is has proved to be very difficult.

can we change a row? Here's where we save data for the selected object

handle the return or enter key being pressed. We override to prevent
