a737a3f5c2 operator bool() and clear(): test for zero and set to zero respectively. 
Checking for zero or non-zero and setting to zero are common operations,
so fast implementations

238cd6078b polynomial: odd/even predicates. 
We use the definition of odd and even consistent with considering x as the
smallest prime factor. That is, an even polynomial has a constant of zero.

e9da8a10bf polynomial: Left and right shift operators. 
Shifting adds or removes a factor of x in the same way that shifting adds
or removes a factor of 2 to integers.

65f7440c2f Minor fixes for polynomial division: 
* Use Boost.Config macros not direct checks on C++ version.
* Use dedicated integer power function - fixes VC10 build failure, also prevents loss of digits when integer type is wider than double.
