createNCPInstance

This function uses an identifier (<code>defnId</code>) to locate
a stored definition in the workspace to create the appropriate
object instance. The instantiated object is assigned the
instanceId and saved under the dataFileName if the latter is
not <code>NULL</code>. This instantiated object may change state between
iterations when a computation executes

Implementing algorithms and fitting models when sites (possibly remote) share
computation summaries rather than actual data over HTTP with a master R process (using
'opencpu', for example). A stratified Cox model and a singular value decomposition are
provided. The former makes direct use of code from the R 'survival' package. (That is,
the underlying Cox model code is derived from that in the R 'survival' package.)
Sites may provide data via several means: CSV files, Redcap API, etc. An extensible
design allows for new methods to be added in the future and includes facilities
for local prototyping and testing. Web applications are provided (via 'shiny') for
the implemented methods to help in designing and deploying the computations.
