Function names

[davebraze]

Function names in this package use lower camelCase. A few functions (transplanted from FDB1), which did not originally conform to that convention, have been renamed so that they comply. The original names are still available as aliases (e.g., function invDnorm with alias inv_dnorm), but the aliases may be removed at some point.

See if I can fix help file index to show only the camelCase versions of function names.
Can this be done with roxygen2 markup? Look into using the following roxygen markup to suppress these entries.

UPDATE 20160630: tried this and it doesn't work for my case. I think it's because I'm using @Rdname to merge the two help sections together.
