annotate libinterp/parse-tree/parse.h @ 16237:70f465930546

rearrange class heirarchy for tree_cell and tree_matrix * pt-array-list.h, pt-array-list.cc: New files. (tree_array_list): New class. * pt-cell.h, pt-cell.cc (tree_cell): Derive from tree_array_list. * pt-mat.h, pt-mat.cc (tree_matrix): Derive from tree_array_list. * oct-parse.in.yy (octave_parser::finish_array_list): New function adapted from octave_parser::finish_matrix. (octave_parser::finish_matrix, octave_parser::finish_cell): Call finish_array_list to do the work. * pt-arg-list.h: Include symtab.h. * base-list.h: Include cstdlib.
