Compatible with Julia 0.6 and 0.7
This release makes the package compatible with Julia 0.7, while keeping compatibility with 0.6, and dropping 0.5
There are some changes in datatypes:
Zero is now a subtype of Integer, instead of Real, which should make it compatible with more functions.
Complex{Zero} is no longer used. Instead, trying to create a Complex where the real part is Zero will result in a Real.
(Minor releases up to v1.0.0 may introduce breaking changes.)
