RelatonGb is a Ruby gem that search and fetch Chinese GB standards.
The standards scraped form:

* GB standards - http://www.std.gov.cn/gb/search
* Social organization standards - http://www.ttbz.org.cn
* Sector standards - http://www.std.gov.cn/hb

NOTE: Unlike the ISO website, the GB websites require the year of publication to be included in the search.
So a standard will not be found successfully through this gem unless the year is included in its document
identifier: for example, not `CN(GB/T 1.1)`, but `CN(GB/T 1.1-2009)`.
