Bring report up-to-date with sqlite3 database and yaml configuration
files.
Updates report command in runnable.py. Moves date arg parsing to utils
module
Report and graph now share an ArgumentParser with shared date options.
parsers.py redid with single default parser that takes configurating
parameters from a yaml file.
Additional parsing configuration can be achieved with the additional_parser
attribute on yaml and rewriting the func and parser method on child
classes of Parser.
func will be called after each transaction is created and the parser
should call the parent parser method or rewrite the entire parser
process.
The parse_data function is now called from the runnable and the parsing
process is now called from there. The parse command can take an optional
bank before is tries to extract it from the filename and multiple paths,
either files or directories.
The Transaction __init__ was fixed to take inputs from previously
initiated Transaction.
Also adds utils.py with helper functions.
