Avoid potential confusion over the round method: ceil, floor, round and trunc no longer accept arguments and so they match their JS Math object equivalents. Removed toInteger as round now handles rounding to integer. Added toSignificantDigits as round no longer rounds to precision. Updated tests accordingly. Calling config without argument no longer throws.
