Need to copy *.topicAssignments from `results` to the directory including corpus when inferring

[sanzam]

STTM/src/models/LDA_Inf.java

Lines 93 to 94 in 5573ed4

	String topicAssignment4TrainFile = trainingCorpusfolder
	+ paras.get("-name") + ".topicAssignments";

I wonder this is intended and fix this if not.
At least I fixed them to make it look for *.topicAssignments file in results directory.
