libpcl and c++ exceptions

てきとーなテストコード書いて問題なかった。

somari(Gentoo Linux / Linux 2.6 x86_64)でテスト。あとでpersianのwin32環境でもテストすること。

実行結果：

ObjHandleTester C-tor :continuable_func
entering continuable_func()
returned from coroutine
ObjHandleTester C-tor :inside try
ObjHandleTester C-tor :throwing_func
ObjHandleTester D-tor :throwing_func
ObjHandleTester D-tor :inside try
caught exception
exiting continuable_func()
ObjHandleTester D-tor :continuable_func
returned from coroutine : 2nd time
exiting...
