forcetable v0.0.2

This is first rlease of forcetable library and second to be created from perock library.
First one to be created from perock is 'prodius' library(cartesian product).

Forcetable calculates cartesian product using 'prodius' library but using fields.
Cartesian product is calculated using fields to create table with records.
It was improved and now looks batter than original version in perock in terms of api.

Splitting perock into smaller libraries could help improve perock or build new one.
Forcetable may be restricted to perock and bruteforce but can be used for other things.
