Put only the implementation of BigInt in src/bigint, mathematical functions
on top of BigInt go to src/math. Some prototypes were moved in order to complete the split, in particular random_integer() is now a static member of BigInt instead of being a global function, and divide() is in divide.h instead of numthry.h
