consolidatePacks

Motivation
The purpose of this package is to remove the '@import' dependence of your package
by consolidating the functions into your package. This may be necessary when the imported
package is decommissioned by CRAN, and you do not want your dependent package to also
be decommissioned.
Methods
The functions in this package recursively retrieve dependencies in your package, and
copy the retrieved functions to the .R file. They also perform other needed
bookkeeping, such as retrieving .Rd files in the man subdirectory.
Results
This package was developed when my package *foodwebWrapper* faced being decommissioned from CRAN because an imported package *mvbutils* was going to be decommissioned. I decided to retrieve foodweb(), which is the one function from *mvbutils* that *foodwebWrapper* needs. Of course the foodweb() dependencies also needed to be retrieved recursively.
Before invoking drDriver(), you need to make sure that both your package and the package containing the dependencies are loaded in the search() path. If the package containing the dependencies contains any functions that are not exported, then the functions must be copied and pasted into the Console in which the driver will be invoked.
Some consistency checking and other tasks are automatically performed when the driver is invoked, including making a working copy of your package directory.
The driver was invoked by
```
drDriver(f="foodwebWrapper",r="/Users/barryzeeberg/personal/
mvbutil_download/mvbutils/",pack2Copy="/Users/barryzeeberg/
personal/hearts/hearts_card_game_bayesian_inference/packages/
foodwebWrapper",verbose=2)
```
Here are some annotated snippets of the transaction log:

```
**Might Need a Small Amount of Manual Tuning before Importing into RStudio . . .**
```
The driver provides the option implement check() at the end of the processing stream. This allows you to catch glitches that you might need to correct by hand before importing into RStudio. In my case, I ran into some missing globals definitions, etc.
```
**Reminders for Wrapping up . . .**
Note that the working version of the package is located in a path name that (at least on mac computer) is "private," and it is difficult to figure out how to get your hands on it. So I provide a brief instruction for how to do so.
Also, if you are happy with the enhanced working package, it is safest to make a copy of it because the driver may inadvertently overwrite this version.
