v1.0.1
Add function showSeitz and beautify the appearance of showLGIrep etc.
Bug fix and update examples.
RotationMatrix[Pi/2, {1, 1, 0}]//rotAxisAngle works wrongly. Update algorithm, use NullSpace directly.
getLGIrepTab: NumberQ ==> NumericQ
Update formatRepMat. Now it can convert Exp[I Pi(1+u)] to -Exp[I Pi u].
Fix a problem of identifyBCHSKptBySG: identifyBCHSKptBySG[46,"a",{-0.1,-0.4,-0.1}] works wrongly because Rationalize[-0.1,0.1] returns -1/9, not the expected 1/10.
