An initial incomplete skeleton for R-code

Need to fix sparse-parsing to not pass through dense matrix format.
Need to re-build documentation for class definitions, accessors, etc.
Need to test on examples. Need to add tests. Need to add print/show
methods. Need to add examples. And so on.
Basic stuff in place. Passes R CMD check without warning

No attempt to read trees yet. No tests yet. Copied example .biom files
for testing, in inst/extdata directory.
Added some tests. Need to get testthat-package to work

Some tests included, know they work. Need to get testthat-package to
work during R CMD check still. Tests fail until testthat-package works
as a testing dependency.
unit tests included, other basic tools

Can probably merge now…
make BIOM and RBIOM all lower case

including class, constructor, etc.
Remove upper-case filenames for conversion to lower case
Add-back the source files, complete with lower-case names
Gave README a markdown suffix, and md link for example
Added some check/test scripts for rbiom pkg
mod/add install/check scripts

Not sure which will be wrapped into the full biom-format package update
tests. Probably the unit_only test or something. Still useful to see
examples for installing the rbiom package or the Rscript call if you
haven't done R scripting before.
rm .Rapp.history, added to .gitignore

minore change to ignore unneeded support files for R IDEs
rm
v0.1.2. dependency updates and some trivial updates. More updates coming...
Updated license information and package dependencies
v0.2.0. Lots of refactoring. Still needs additional tests, new pkg check
some name changes
Updated  doc, added accessors. Needs validity methods, tests. Needs to pass checks.
v0.2.3 passes tests, checks. writes biom files.
Added a demo Rmd/HTML to the documentation
v0.2.4 Rv3.0.0 style Rmd vignette support added. Both unicode ex files and handling need revision.
