Fits all distributions, returns an object of a special class. Prints nicely to show the statistic of the fit, and which one is the 'best fit'.

fitalldistributions(angles, fitmethod = "loglik", 
distributions = c('twoparbeta', 'ellipsoid', 'rotatedell', 'planophile', 
'erectophile', 'plagiophile', 'extremophile', 'spherical', 'uniform'), ...)

`angles`	Vector of angles (0 - 90 degrees)
`fitmethod`	'loglik' or 'chisq'.
`distributions`	By default, all implemented distributions.
`...`	Further parameters to ftheta (none as of now).

In most cases, the two-parameter beta distribution provides the best fit, because of greater flexibility.

Object of class angledistlist, which has print and plot methods.
