legend.m: Clean up implementation.
* legend.m: Rename variable "fig" to "hfig" for clarity. Remove unnecessary
error() that should never happen (someone will always report it if it does).
Add more comments to try and explain code. Rename property "handle" to
"__axes_handle__" which points from legend to associated axes. Add new
property "__legend_handle__" to associated axes which points back to legend.
Replace complicated searches for an existing legend object with try/catch
block looking for "__legend_handle__" property. Remove redundanc code.
Rename "oldfig" to "origfig" for clarity. Rename "curaxes" to "origaxes"
for clarity. Important: Make new legend object's parent the same as the
parent of the associated axes. This makes legends work for things like uipanel,
not just figures. For performance, limit search for htdel text object to
a depth of 1.
* legend.m (cb_legend_update): Rename "handle" to "__axes_handle__". Remove
unnecessarily complicated code to get hplots from existing legend.
* legend.m (cb_restore_axes): Set "__legend_handle__" on associated axes
to [] when deleting legend.
* __getlegenddata__.m, axes.m: Rename property "handle" to "__axes_handle__".
* __errplot__.m: Remove unnecessary ancestor() call to find axes.
Replace search for legend with try/catch on "__legend_handle__" property.
* __plt__.m: Replace search for legend with try/catch on "__legend_handle__"
property.
* hdl2struct.m: Replace search for legend with try/catch on "__legend_handle__"
property. Replace search for colorbar with try/catch on "__colorbar_handle__"
* __gnuplot_draw_figure__.m: Rename property "handle" to "__axes_handle__".
Replace search for legend with try/catch on "__legend_handle__" property.
* __gnuplot_print__.m (get_figure_text): Simplify determination of legend,
it is just an axes object with tag set to legend.
