Initial commit of RaggedArray module/package
A little bit of testing code
sapply now working for R & user-included C++ functions, with and without resizing.
Fixed bug in grow, adding unit tests using testthat
Testing timings of functions called from R vs xptr lookup hackery
Minor changes to sapply
Nice set of timings tests.  Tried making an XPtr-factory, no luck.  Consolidate alloc functions.  Need to consolidate sapply and sapply_cpp loops into sinlge worker function?
Added convenience script
No method for sapply??
working
working.  only zero out extra elem. added back prep.
moved repeated code into worker function grow_assign_sapply, reordered methods.
Moved extra scripts into inst/tests, added test.
Adding moved files back to repo
Trying to combine sapply and sapply_cpp.
Combined sapply_master working.  Changed names of public interface, added mapply, wrote tests for R mapply versions.
Added docs via roxygen2.  Having problems with 'R CMD check' due to recursive call to R CMD check via sourceCpp
Cleaned up user defined functions in userFun.cpp, added macros and examples of mapply.  Added tests.  Segfault for sampling large number of x??
Working on paths for testing sourceRcpp.  Fixed example source
Modularized unit tests, fixed compilation issue.  Example functions moved to inst/examples, test functions are links to these.  Updated timings.R, moved to examples.
