compare_hurdle2other: compare a glmmadmb hurdle to non-hurdle models
In prestevez/vicarp: Victimisation Analysis and Reporting

This function compares the joint parameters of a hurdle model specified by two distinct models (e.g. a binary and a truncated count model) with the parameters of a non-hurdle count model. No checks are made to ensure that the models supplied are comparable. The function is designed for glmmADMB models only.

1 2	compare_hurdle2other(mlogit, mcount, ..., modnames = c("Hurdle", "Negbin.", "ZINB"))

`mlogit`	a binary model
`mcount`	a truncated count model
`...`	a series of at least one comparable glmmadmb model
`modnames`	a vector of names for the models supplied. `mlogit` and `mcount` correspond to "Hurdle", while the rest of the models supplied in `...` correspond to the rest of the names. If only one model is supplied in `...`, only the first two names are used.
