Expand and improve tests for binary operators: add scalar-array case
Fix problems in binary operators that made new tests fail
Add #EPS_FLOAT and #EPS_DOUBLE (for FLT_EPSILON and DBL_EPSILON)
Remove some superfluous whitespace; change an int to an enum
Change the basis of greater-than/lesser-than for complex numbers.
Used to be based on the absolute value, so +1 < -2.
Is now based on projection on 1+i, so +1 > -2 and +i > -i.
Add 3rd test case for binary operators
Update manual for changed ordering of complex numbers
Increase version to 1.0.4
