import tryalgo

[xtof-durr]

Why can't we import directly
from tryalgo import opt_bin_search_tree1, decode_root_matrix_to_level
but need to write
from tryalgo.dyn_prog_tricks import opt_bin_search_tree1, decode_root_matrix_to_level
?
In other words at what place are the modules moved one level up for export?
