• calculateFirstResultOffset()
• getCurrentPageFirstResultOffset()
• calculateLastResultOffset()
• getCurrentPageLastResultOffset()

all need reworking. They are calculating wrong.

• On a page with 0 results calculateFirstResultOffset returns 1.
• getCurrentPageLastResultOffset doesn't take into consideration half responses on the last page.

This might be a good thing to write tests for.

Looking at this again the getCurrentPageFirstResultOffset and getCurrentPageLastResultOffset are used for the doctrine query and templates. Might need to split these out.
