# Masters of the Universe Coding Assignment
As a business user I need a tool that reads an accounting log in csv format that sums up all amounts per account_id and month and outputs a csv with summaries so we can double check the bookings easily.
## Acceptance Criteria
* the tool accepts 2 file names (input and output)
* output is a csv file with following fields
* MONTH - the month of the booking in format yyyy/mm
* ACCOUNT_ID - an ACCOUNT_ID from the input file
* SUM_OF_AMOUNT - the sum of all input amounts for a ACCOUNT_ID per MONTH
* empty lines in the input file are ignored
* the amount from the input is summed up, grouped by ACCOUNT_ID and MONTH
## Format for the input csv
* separator is a comma ','
* the file has a header line
* there are no quotes used
* there can't be a comma in one of the fields
* the file may contain empty lines (no character or just white spaces)
* the file is encoded in UTF-8 without BOM marker
* the file has 4 columns
* TIME_STAMP - time of booking in format yyyy-mm-dd hh:mi:ss
* ACCOUNT_ID - Integer number
* EMPLOYEE - String (name of employee)
* AMOUNT - floating point number
## Sample files:
* good_input.csv - a sample input file that has no validation error
* good_output.csv - expected output from processing good_input.csv
## Nice to have
* the tool writes a error file with rejected records
* the header and each line is checked for the expected number of columns
* every field is trimmed from whitespace
* input record validation is done
* no field may be empty after trimming
* TIME_STAMP must be in expected format
* only valid ACCOUNT_ID are accepted, list of IDs:
* 10101
* 10302
* 10506
* 10780
* input lines that are rejected in validation are written to an error csv file
* the error records have an additional column with a reason for being rejected
## Sample files for 'Nice to have':
* input_with_error.csv - a sample input file that has all kinds of validation problems
* input_with_error_output.csv - expected output from processing input_with_error.csv
