DISC compatibility for FAVE-extract

[scjs]

Update FAVE-extract for compatibility with DISC (CELEX) phonetic alphabets for use with non-North American dialects

[scjs]

Are there Plotnik codes for all of the DISC codes? FAVE has a few explicit references to ARPAbet, but one way to make it more compatible (and add other transcription systems down the line) might be to convert all of these to the Plotnik codes internally. DISC and ARPAbet both have codes that the other one doesn't unfortunately. @kylebgorman

I think this could fall under a larger goal of mine to make FAVE operate over any arbitrary label set. The way I see this working is:

1. Moving translation into plotnik codes out of FAVE-extract, and into a pre-processing procedure on the output of FAVE-align.
2. Replace plotnik contextual coding with simply including segmental and lexical information in the FAVE output.
3. Providing FAVE-extract with a list of vowel phones and measurement point heuristics.
4. Providing FAVE with means and covariances for the specialized phone set.

Parts (1) and (2) should be easy enough, part (3) is probably going to be really difficult, and part (4) will require some investment on the part of the researcher at the start of their project, but shouldn't be so bad. The effect of the "priors" on the overall formant estimation process is relatively weak, so only about 5 or 10 measurements per vowel should really be necessary.

@JoFrhwld was this resolved in f5b7e70? If so this can be closed.

No, I think these were commits for windows compatibility. The heavy lifting for allowing DISC codes is spread across a few functions, but key among them is isVowel() which still references the global VOWELS variable.

Also, a ton of plotnik.py is implicated.
