Transition from AYACC/ALEX to Flex/Bison

by genome analysis when using non-flat classes

new version of easea (without alexyacc) is equivalent to the old one

in CMakeLists.txt (-i means that the lexer won't be case sensitive)

Also modified the Makefile to compile EaseaLex.l and EaseaParse.y with
Flex and Yacc (and not alexyacc)

of alexyacc, and remove alexyacc code source

(it may still need some improvement but it pass regression test for non cuda test)
