Input Method

If you want to implement an input method, the things you need to care about is the "Do-In put" Phase and "Get-Candidate" Phase, usually, we put code that are related to update UI into "Get-Candidate". For input methods in Fcitx, we require input method to return all the candidate at once. Some other framework maybe just return by page, fcitx didn't prevent that, but return all candidate at once have some obvious benefit. If we doing so, we don't need to keep every page for the same size, we can split into different page by the "length" of candidate. This would be especially important if you are working a small device (phone, for instance).
