trunk: changing norm_vars file in experimental directories to cmvn_opts, for greater flexibility; some minor fixes; change default tolerance in extract-segments to 0.5 seconds (was zero, since April).

sandbox/language-id: Minor fix to LogisticRegression::SetWeights(); the variable 'classes' is now properly copied to 'class_'

git-svn-id: https://svn.code.sf.net/p/kaldi/code/sandbox/language_id@3818 5e6a8d80-dfce-4ca6-a32a-6e07a63d50c8

sandbox/language-id: In logistic regression code: fixing bug in LogisticRegression::GetLogPosteriors() (vector version). Updating LogisticRegression::SetWeights() (a private function used in testing) to include the class map and updated logistic-regression-test so that it runs without failing, although it doesn't yet test the new mixture model directly.

sandbox/language_id: Replaced language refering to 'posteriors' with 'log posteriors,' to match the reality of what is computed. For instance, GetPosteriors() was replaced with GetLogPosteriors(). Subsequent changes to variables called posterior are replaced with log_posterior. Updated logistic-regression-test.cc to use BaseFloat type instead of double to match type changes in the LogisticRegression method declarations.

sandbox:language_id: In LogisticRegression: Adding L2 regularization, refactoring code, and adding unit tests.

sandbox/language_id: Adding logistic-regression-eval for reading in a model trained by LogisticRegression and writing posteriors and scores.

sandbox/language_id: Adding LogisticRegression class which uses L-BFGS internally. Logistic regression is the standard classifier for language-id.
