0.2-01 - 2012-10-17
* Lot of changes for this version, including:
  * Coe class replaces former Nef and now handles eFourier, rFourier and tFourier methods.
  * hqual, hquant, hpow and hcontrib (formerly harm.qual, harm.quant, etc.), morpho.space, dudi.plot, etc. now handles efourier, tfourier and rfourier through the "method" argument.
  * Worked a lot on helpfiles.
