MEWS 1.1.3

• Added shift_function to mews.weather.alter.Alter which shifts an entire
  time series mean value by "m" while keeping the timeseries minimum value constant
• Added recalculate_psychrometrics to the "mews.weather.alter.Alter" class so that changes
  to a psychrometric variable shift other psychrometric variables.
• Added EPW_DATA_DICTIONARY to mews.constants.data_format and several other
  improvements to assure EPW maintain the correct data format.
• Added changes to mews.epw.epw focused on assuring that correct EPW files
  are written so that any other program can read them.
