bc77596f23 Improve calculation of phase probabilities when normalizing so they really should add up to 1. 
Allow slight tolerance in checking for sum of phase probabilities.
Add missing call to normalize in iterator constructor.
Remove asserts that duplicated the error handling code - better to provide consistent behavior via the error handlers.
Add comment to examples about other containers working equally well.

fb835eb029 fix rounding errors 
- the direct predecessor/successor for 0.5/-0.5 was formerly wrongly
   rounded to 1.0/-1.0 rather than 0.0

 - integral numbers of the format 1xxxxxx1 filling mantissa completely
   were formerly rounded to the next integral away from zero

3c07a49aac Don't check long double capability for BOOST_CSTDFLOAT_xx. 
For example IA-32, those macros suggest long double as 80-bit floating
  point type, however some math runtime implementations are broken for
  long doublle even if supported by compiler (e.g. FreeBSD 9, ...).
