Only single thread is used in 'Sampler'

I think this is the problem with lambda expression code.
Please check that logic and if there is error semantically, fix them using another C/C++ function.

Refer to this code below:

WICWIU/WICWIU_src/DataLoader.hpp

Lines 212 to 228 in be6c12d

	template<typename DTYPE> void DataLoader<DTYPE>::StartProcess() {
	// Generate thread for Dist - DistributeIdxOfData2Thread()
	// Generate thread set for Process -
	m_nowWorking = TRUE;
	m_aThreadForDistInfo = std::thread([&]() {
	this->DistributeIdxOfData2Thread();
	}); // lambda expression
	printf("Generate dataloader base thread\r\n");
	for (int i = 0; i < m_numOfWorker; i++) {
	m_aaWorkerForProcess[i] = std::thread([&]() {
	this->DataPreprocess();
	}); // lambda expression
	printf("Generate worker[%d] for data preprocessing\r\n", i);
	}
	}
