Fixed string spacing issue
Fixed minor formatting issue where 60 seconds wasn't being shown as '1:00'
made DataColumnView title a public readonly property mainly for debugging (when we dump a column from another class, we can get the title information
Fixed bug where data label was not centered in the view.  Normally, this wasn't seen, but if the columns were different widths (e.g. in the intensity view VDOT <= 39 had one pace that was 10:00 or greater and in VDOT>=40, there was no pace greater than 9:59 so the width of the label was different), it looked wrong.
Added MAX_VDOT define for internal support.  This is used in debugging.  no functional change
Fixed bug in viewcontrollers where the dataScrollView had its frame set incorrectly.  Most of the time, it looked fine, but when switching between the view controllers via the tab, when the VDOT was < (max - 3), the placement became off.  I believe it was because the setting of the frame was self-referential when it shouldn't have been.
