Executes a function call with option to ignore unused arguments.

## Default S3 method:
doCall(.fcn, ..., args=NULL, alwaysArgs=NULL, .functions=list(.fcn),
  .ignoreUnusedArgs=TRUE, envir=parent.frame())

`.fcn`	A `function` or a `character` string specifying the name of a `function` to be called.
`...`	Named arguments to be passed to the function.
`args`	A `list` of additional named arguments that will be appended to the above arguments.
`alwaysArgs`	A `list` of additional named arguments that will be appended to the above arguments and that will never be ignore.
`.functions`	A `list` of `function`:s or names of functions. This can be used to control which arguments are passed.
`.ignoreUnusedArgs`	If `TRUE`, arguments that are not accepted by the function, will not be passed to it. Otherwise, all arguments are passed.
`envir`	An `environment` in which to evaluate the call.
