Consistent Parameter Names

[jzwart]

Rename fitted parameters that are returned when using attr() to make consistent among models. For example, C[1] and C[2] in the bayes model vs. gppCoeff and rCoeff in the mle model.

This could break old code (thinking primarily of LM's users, but we'd also have to look throughout the package code, like in metab(), to make sure any change is consistent).

I agree that this seems desirable.

Alternative might be to add a getCoef() function with a 'method' for each type of model (except BK). But your suggestion seems better to me --- just need to recognize that people who used old versions won't be able to run old code with new version. This incompatibility might warrant incrementing the major version number. Therefore, perhaps such a change should be implemented when we have more significant changes to implement, too.
