- Added v-factor generalization to DEMA (thanks to John Gavin)
CHANGES:

- If ‘ratio’ is specified in EMA but ‘n’ is missing, the traditional value of ‘n’ is approximated and returned as the first non-NA value (thanks to Jeff Ryan)
BUG FIXES:
- Fix to stoch() when maType is a list and ‘n’ is not set in the list’s 3rd element (thanks to Wind Me)
