v2.0.0

Browse Source 
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.
