%DRAWLABELS3D Draw text labels at specified 3D positions.
%
% drawLabels3d(X, Y, Z, LBL) draw labels LBL at position X and Y.
% LBL can be either a string array, or a number array. In this case,
% string are created by using sprintf function, with '%.2f' mask.
%
% drawLabels3d(POS, LBL) draw labels LBL at position specified by POS,
% where POS is a N-by-3 int array.
%
% drawLabels3d(..., NUMBERS, FORMAT) create labels using sprintf function,
% with the mask given by FORMAT (e. g. '%03d' or '5.3f'), and the
% corresponding values.
