BNFParser :: analyzeFile - Analyze file
The function analyzes data in the passed file and creates a hierarchy of BNFNode elements (symbols). Each BNFNode element refers to the symbol or token and to a sub string in the file, that contains the value for the symbol.
The function will parse the file according to the syntax defined in the BNF (top-symbol) or according to a given symbol of the syntax. When the file contains errors, the function returns an invalid BNFNode (BNFNode::isValid()). In this case an error text is returned by function BNFParser::lastError().
