Define Top-down parsing Techniques

Top-down parsing can be observed as an attempt to find left-most derivations of an input-stream through searching for parse trees using a top-down expansion of the specific formal grammar rules. Tokens are consumed to right from left.

Inclusive choice is employed to accommodate ambiguity by expanding all choice right-hand-sides of grammar rules.
