SuperTab complete for neocomplcache

As I said in my previous post, neocomplcache is a very powerful vim plugin.
It incoporates the funtionality of SnipMate and  AutoComplPop while providing efficient search
for potential completion items.

However, SuperTab does not support neocomplcache. It is very bad since I like to tab complete
everything, including snippets. Here is the solution -- put the following in you .vimrc:

imap  <silent><expr><tab>  neocomplcache#sources#snippets_complete#expandable() ? "\<plug>(neocomplcache_snippets_expand)" : (pumvisible() ? "\<c-e>" : "\<tab>")
smap  <tab>  <right><plug>(neocomplcache_snippets_jump) 
inoremap <expr><c-e>     neocomplcache#complete_common_string()

The above setting allows you to trigger a snippet with "tab" key when possible. If not, it will simply trigger omni completion. I set it to complete the longest common string. It is just a personal taste. You can set it to other type of completion as well.
