-/// LMInstantiator is a facade for managing a set of models including
-/// the input method language model, user phrases and excluded phrases.
-///
-/// It is the primary model class that the input controller and grammar builder
-/// of vChewing talks to. When the grammar builder starts to build a sentence
-/// from a series of BPMF readings, it passes the readings to the model to see
-/// if there are valid unigrams, and use returned unigrams to produce the final
-/// results.
-///
-/// LMInstantiator combine and transform the unigrams from the primary language
-/// model and user phrases. The process is
-///
-/// 1) Get the original unigrams.
-/// 2) Drop the unigrams whose value is contained in the exclusion map.
-/// 3) Replace the values of the unigrams using the phrase replacement map.
-/// 4) Replace the values of the unigrams using an external converter lambda.
-/// 5) Drop the duplicated phrases.
-///
-/// The controller can ask the model to load the primary input method language
-/// model while launching and to load the user phrases anytime if the custom
-/// files are modified. It does not keep the reference of the data pathes but
-/// you have to pass the paths when you ask it to do loading.
