Bumped version number to 0.2-0
steelStrain demo now plots best-fit surface
Changed documentation to use R 2.15

Most .Rd files only changed the ordering of a few lines.
Fixed: had double-counted .Model in docs

I had written
@S3method getLower.Model Model
instead of
@S3method getLower Model
which is boneheaded.
Made documentation compatible with NAMESPACE

- Added export statements for print and clone method
- For now, I have to manually add the constructors to NAMESPACE, because
  they use R.oo instead of roxygen.
- Gave in to the Collate message in the DESCRIPTION file, which the
  newer devtools generates
Made public R.oo play nice with NAMESPACE

Apparently I need to export both the generic function and the fully
qualified name for each class, or else the R.oo syntactic sugar won't
work.  This commit doesn't represent a working state, because I need to
fix the private files, but it should be OK for the public ones.
Fixed oversights in documentation

- getVaryingParamNames: I had written roxygen comments, but I forgot to
  write "#'" instead of "#" so roxygen would actually see them
- setParams.Covariance had been missing export and S3method tags; these
  are now added
Fixed demo (removed syn-sugar for private methods)

R.oo provides syntactic-sugar field access: e.g., instead of
  Method(this=object, ...)
you can write
  object$Method(...)
which is a more "object oriented" way of doing things.  Unfortunately,
this seems to rely on the fully qualified method name, i.e.
  Method.class
being exported to the namespace.  Private methods should *not* be
exported to the namespace.  Hence, we can't use the "nice" way to access
private methods.
Use the "modern" approach for sd() on data.frame
steelStrain demo: show TRUE datapoints in gap
Removed redundant 'gppois:::' qualifiers

I was a little overzealous adding 'gppois:::' before each private
method.  This appears to be unnecessary for code that is WITHIN the
package.  (Code "outside" the package, such as the steelStrain.R demo,
still needs this qualifier.)
Setup structure for unit tests

Note: there is no reason to believe these tests will run, or that they
are reasonably complete.
Setup infrastructure for unit testing

Also, started copying some of my old unit tests.  But it's changed
enough to make this a non-trivial task, so I'm deferring the rest until
I can do it properly.
Made script to reproduce steelStrain from raw data

I want my data generation to be more reproducible and transparent, so I
made a script that does what I want it to with the raw data for the
steelStrain dataset.  It will be tracked in github, but the datafile
will be excluded from the package build (it's 5.1 MB; that's too big).
Setup infrastructure for unit testing

I started copying some of my old unit tests.  But it's changed enough to
make this a non-trivial task, so I'm deferring the rest until I can do
it properly.

Also, I augmented the steelStrain dataset to include exy and eyy columns
in addition to exx column.
Modified tests so Dataset passes

The 'SameX' test apparently tested a feature which no longer exists.

Also, I get warnings about being unable to find datasets when I run the
tests, but the tests pass.  So I'm not sure what that's about...
Innumerable changes to pass R CMD check
Dependency bump to R >=2.14.0

The package now thoroughly uses the new NAMESPACE-based approach.  Given
that even Debian installs can easily obtain recent versions of R, I see
no reason to cater to old versions.
Added datasets from JAC paper
Fix syntax error in R-dependency

Boneheaded... needed a space before the number
