Detailed Description

Find maximum-likelihood weights for interpolating several probabilistic models.

interpolate_v2: Find maximum-likelihood weights for interpolating several probabilistic models, where the models are described by their output on a common set of items (.fprobs file), previously derived from a common text file. "-test_last nnn" means that the last nnn items of each model will be used for testing. "-test_all" means _all_ items will be used for testing. "-test_first nnn" means that the first nnn items of each model will be used for testing and the last nnn items of each model will be used for training. "-test_cv" means to run in cross-validation mode, where each half of the test items will be used for training and testing, and the resulting PPs will be combined to give an overall PP value. If a partition of the items is induced via a "tags" mapping, separate weights will be calculated for each tag.

In "test" mode, run thru the main loop only once, to compute the test PP. The initial lambdas may be read from a file. For non-test-mode, they default to 1/#-of-models.
