Parse options and assign values

Combines opt_get and assign for convenience.

opt_assign(x, pos = 1, inherits = FALSE, name = x, ...,
  assign.na = FALSE)

opt_assign_all(x, ..., assign.na = FALSE)

`x`	character or list; variable names or alias. If no coercion is done, and the first element of a character vector of length greater than one will be used, with a warning.
`pos`	where to do the assignment. By default, assigns into the current environment. See 'Details' for other possibilities.
`inherits`	logical; should the enclosing frames of the environment be inspected? This is argument is supplied to `base::assign()`.
`name`	character; name(s) of option as passed to `opt_get`. (Default: 'x“)
`...`	arguments passed to `opt_get`
`assign.na`	logical; whether `NA` can be assigned. (Default: `FALSE`) `opt_assign` combines `opt_get` and `assign` in one call. The `name` argument is passed as `opt_get(name=...)`; it defaults to `x` so it is generally not needed. `opt_assign_all` does multiple assignments but does not allow for a names arguments. Values are names by `x`.

  opt_assign( "foo", opts=c("--foo","bar") )
  opt_assign( c("foo","f"), opts=c("--foo","baz") )
