Amnon Heiman bc854342e7 approx_exponential_histogram: Makes the implementation clearer 
This patch aim to make the implementation and usage of the
approx_exponential_histogram clearer.

The approx_exponential_histogram Uses a combination of Min, Max,
Precision and number of buckets where the user needs to pick 3.

Most of the changes in the patch are about documenting the class and
method, but following the review there are two functionality changes:

1. The user would pick: Min, Max and Precision and the number of buckets
   will be calculated from these values.
2. The template restrictions are now state in a requires so voiolation
   will be stop at compile time.
