I tried the latest feature/capf branch for a while and it basically
works well. I think it's worth integrating into AUCTeX.

I'm aware of two issues currently.
1. It throws the following notifications repeatedly in the echo area
after I typed a character after parentheses like "()":
Company: An error occurred in auto-begin
Company: backend company-capf error "Scan error: "Unbalanced parentheses", 
7426, 6790" with args (prefix)
2. It throws the following error after something like "\sqrt[3]". It
seems that it doesn't like string literal inside "[]" for TeX symbol
specifications.
Company: An error occurred in auto-begin
Company: backend company-capf error "Wrong type argument: symbolp, "Root"" with 
args (prefix)

I hope these reports are helpful for you.
