predict.samHL: Prediction function for S3 class '"samHL"'
In SAM: Sparse Additive Modelling

Predict the labels for testing data.

1 2	## S3 method for class 'samHL' predict(object, newdata, thol = 0, ...)

`object`	An object with S3 class `"samHL"`.
`newdata`	The testing dataset represented in a `n` by `d` matrix, where `n` is testing sample size and `d` is dimension.
`thol`	The decision value threshold for prediction. The default value is 0.5
`...`	System reserved (No specific usage)

The testing dataset is rescale to the samHLe range, and expanded by the samHLe spline basis functions as the training data.

`values`	Predicted decision values also represented in a `n` by the length of `lambda` matrix, where `n` is testing sample size.
`labels`	Predicted labels also represented in a `n` by the length of `lambda` matrix, where `n` is testing sample size.
