[phpesp-dev] Little things

[Stefan C. <sch...@ea...>]

I've noticed that sometimes one says :

- a "realm" when he means a "group"
- a "field" for a "question"
- a "form" for a "survey"

I'll fix them as I get them. If you agree, let's be consistent : 

- respondent : someone who answers a survey
- designer :  someone who makes a survey
- survey : a survey
- question : a question, part of a survey
- group : a set of people or a set of survey
