seems like nothing leave, zhang can parse and serve beancount's example data without any error.

based on @Harry-Chen 's suggestions, we will seperate some tickets to enhance the exprience of usage of pushtag and poptag directives.

• strict mode for beancount's pushtag and poptag #143
• duplicated pushtag directives for same tag #144

and this PR will only focus on the integration of beancount syntax. make sure zhang can work with beancount file without any changes.
