atSource
Run Commands in Another File Using Relative File Paths

### Description

This lets a test file "source" another file in the same directory (or a related directory) as the current test file. I.e., relative paths are relative to the current file's directory, not R's current working directory.

### Usage

    atSource(file, what = c("source", "init", "pop", "clear", "cur_dir"), env)

### Arguments

file | The name of the file to run. The name will generally be a relative path, like "makeData.R" or "setups/makeData.R" and the root of that relative path will be the directory containing the file that contains the call to atSource.
what | The user should not use this argument, which should be used only by the assertionTest function to control and query the state of test environement.
env | The user should not use this argument, which should be used only by the assertionTest function to control the state of test environement.

### Details

This function depends on assertionTest() to manage the stack of files. It will not would if you evaluate the test file calling atSource via eval(parse(testFile)) or source(testFile).
Value
Nothing useful. This is used only for its side effect of creating objects used in several test files.
