distinguish different phonemes. [+/- nasal] is the distinguishing

feature in the minimal pair of phones [n][d]. the processing of

multiple rule sets is accomplished in this project via the notion

of an 'epoch.' at least one epoch must be defined, which takes as

its input the initial lexicon. any additional epochs must have

their input lexicons configured by the user, but they will default

to running in sequence. what this allows is for 'snapshots' of

lexicons between suites of rules (analogous to 'intermediate'

phases in historical linguistics, such as old english>middle
