-// This function searches for a terminal in the dictionary by its address.
-// Due to the fact that words are ordered in the dictionary in a strict breadth-first order,
-// it is possible to check for this with advantageous complexity. For each node, we search
-// for groups with children and compare the children address with the address we look for.
-// When we shoot the address we look for, it means the word we look for is in the children
-// of the previous group. The only tricky part is the fact that if we arrive at the end of a
-// node with the last group's children address still less than what we are searching for, we
-// must descend the last group's children (for example, if the word we are searching for starts
-// with a z, it's the last group of the root node, so all children addresses will be smaller
-// than the address we look for, and we have to descend the z node).
-/* Parameters :
- * root: the dictionary buffer
- * address: the byte position of the last chargroup of the word we are searching for (this is
- *   what is stored as the "bigram address" in each bigram)
- * outword: an array to write the found word, with MAX_WORD_LENGTH size.
- * outUnigramProbability: a pointer to an int to write the probability into.
- * Return value : the length of the word, of 0 if the word was not found.

+// for PtNodes with children and compare the children position with the position we look for.
+// When we shoot the position we look for, it means the word we look for is in the children
+// of the previous PtNode. The only tricky part is the fact that if we arrive at the end of a
+// PtNode array with the last PtNode's children position still less than what we are searching for,
+// we must descend the last PtNode's children (for example, if the word we are searching for starts
+// with a z, it's the last PtNode of the root array, so all children addresses will be smaller
+// than the position we look for, and we have to descend the z node).
