Classless Inter-Domain Routing (CIDR) Notation Calculator

> CIDR notation is a compact representation of an IP address and its associated network mask. The notation was invented by Phil Karn in the 1980s. CIDR notation specifies an IP address, a slash ('/') character, and a decimal number. The decimal number is the count of leading 1 bits in the network mask.

Why?

> Eventhough I am not a network guy but understandibg these network concepts are fun. So, I wanted a write a CIDR calculator app (Web, Mobile, and Desktop) and figured I started with a shared module that I can use.
