CAB subnode identification



BNF grammar definitions:

 id ::= ( "" | <array-index> "." ) <regular-id> 
 array-index ::= "[" <integer> "]" <opt-array-index>
 opt-array-index ::= <array-index> | ""
 regular-id ::= <dic-name><opt-array-index> ( "" | "." <regular-id> )
 dic-name ::= <a sequence of any character except of ".">


A subnode of CAB dictionary is identified by a string of <dic-name> syntax. A subnode of CAB array is identified by an integer index.

Additionally a generic multi-level subnode identification is supported through a string of <id> syntax.
Examples:
"name1" "[0]" "name1.name2[0][1].name3"
"[0].name4[1]"
