New methods added to the `math` package: `math.eulers_totient` and `math.count_divisors`.
1.2.1
The `math.prime_generator` was not working correctly if the parameter `p_min` was an even integer greater than two.
1.2
New packages `dicts` and `dates`. `dates` provides an easy to use timer class to mesure the execution time of a block of code. The `dicts` package provides a function to do a safe deep inspection of nested dictionaries.
1.1
A new package `file` contains some functions to extract values of any type by reading a file line by line. This was originally implemented to work easily with Google Code Jam's input files.
1.0
Initial version of `utools`. Some mathematical functions are offered by the `math` module: * primality test * prime generator * divisors calculator * binomial coefficient
