Add Unary Operator Support to PintArrays #221

Closed

Currently the below example does not work:

from pint_pandas import PintArray

p = PintArray(np.array([1,2,3], dtype=np.float64), 'm')
p1 = -p

Instead you must multiply by a negative scalar as follows:

p1 = -1*p

I had hoped to get this working with #160 , but that's still a while off...

Alternatively PintArray.__pos__ and PintArray.__neg__ could be implemented for -p and -p .
The unary tests in #160 can be copied.
