Parse, normalize & aggregate list of IPv4 networks/addresses

This program:

1. parses text file with set of ip addresses and/or networks,
2. normalizes them,
3. auto aggregates (optionally),
4. saves result set.

Example of normalization & auto aggregation with default settings:

File contains: 267593 networks/IPs with 15974399 IPs coverage.
After normalization: 63642 networks/IPs with 14740205 IPs coverage.
After auto aggregate: 15919 networks/IPs with 15501918 IPs coverage. Removed 75% records (47723). Add 5.2% IPs coverage (761713).
