… bug that confused me: if I DO NOT use the colorful log, then some of the tail logs won't be displayed, anyone could help me?

Seperate the big file to some small files, it maybe easier to maintain.

*** I don't know why MCDVTTextStorage must use method_exchangeImplementations to hook the original method,
not like others.

*** I don't known why this version's Log filter is so bad.

…should not remove the pattern object in -[MCLog searchFieldDidEndEditing:] but in -[MCLogIDEConsoleArea _shouldAppendItem:] when searchFile.text is empty

 I found the cause of Issue yuhua-chen#39: In last version of yuhua-chen/MCLog, use GCD and buffer_queue to wait the coming unfinished log content, so there is a risk: we operate the unprocessedOutputInfo in two threads.
In some situation, if we set value to unprocessedBuffer ( the code actually is " [unprocessedBuffer release]; unprocessedBuffer = newVal;" ), if method "outputForStandardOutput:"(thread 1),  after the call of "[unprocessedBuffer release];" thread 2(buffer_queue) go into MCOutputUnprocessedBuffer and get the value of  unprocessedBuffer, there would be EXC_BAD_ACCESS.
