days - do not stabalize periods spacified in days

Browse source 
weeks - calculate start date for finding period using remainer 400/periodlength to reduce number of iterations (perhaps this ought to follow the same conventio as years months and quarters)

add sample period command tests
add add day period tests for forecasts and budgets
add week period tests for forecasts and budgets - these do not change
