v.0.2.5

Improved error reporting. Type SQLParsingError got method toString to properly format itself, plus inspect override that calls toString for proper output into the console.

Example of the console output when doing console.log(error):

SQLParsingError {
    code: parsingErrorCode.unclosedQI
    message: "Unclosed quoted identifier."
    position: {line: 1, col: 6}
}
