added: Big::Sgn - the 'sign' from the value (-1,0,1)
added: global functions Mod and Sgn too
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@19 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: bad sizes in tables in some 'Set...' methods in the Big class
fixed: Big::FromInt(Int<int_size> value) - the sign must be set at the end because SetSign
checks whether there is zero and depends on it sets the sign or not
(this was the stupid error which causes sometimes the errors 'overflow during printing')
fixed: Big::SetMin - the sign must be set at the and
changed: Big::Pow can use the reference now (the problem was actually with the Big::FromInt)
added: a namespace 'auxiliaryfunctions' (in ttmath.h)
added: ATan - arc tan, ACTan - arc ctan
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@17 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed kind of templates in ttmath.h (template<class ValueType> is now)
added TTMATH_RELEASE macro
added TTMATH_ prefix into macros
changed multiplication in UInt type (now we can use both algorithm in the same time)
added ExceptionInfo, ReferenceError and RuntimeError classes
now TTMATH_ASSERT throws another type of object
added TTMATH_REFERENCE_ASSERT (it is instead of MATHTT_THIS_ASSERT)
