Create a parse tree from an array of terms representing an expression.

Test

Parse the expression:

``` v_sub a_is v_array as v1 d_== v2 a_then v3 d_plus v4 a_else v5 d_== v6 a_then v7 d_minus v8 a_else v9 d_times b v10 a_+ v11 B

```

to get:

is sub as array then == else v1 v2 plus then v3 v4 == else v5 v6 minus times v7 v8 v9 + v10 v11
