rim 0.5.1

Minor

knitr-engine now supports chunk options echo, eval and include, a description can be found in the documentation page
fixed several issues related to changes with Maxima version 5.46.0

knitr-engine now supports plotting commands: plot2d(), plot3d(), draw(), draw2d(), draw3d() (and others that are based on those mentioned), depending on the output format (PDF or HTML), plots are saved as PDF or PNG respectively
Added inline output function to be used when knitting RMarkdown documents.
Restructured the return type of the get function: Instead of a character string, now a list is returned storing every output format of the result including both with and without reference labels.
Added a global option handling function maxima.options() and removed individual option setting functions maxima.setformat(), maxima.engine.format() and friends
Whether reference labels are printed or not when knitting a RMarkdown document can now be controlled by setting maxima.options(engine.label)

fixed issue #16. code chunks that contain commands spanning multiple lines are now printed as-is (except for empty lines, which are removed) with the preceding input reference label
fixed the issue #17, caused by a socket-read-write-concurrency conflict which led to split lines read from Maxima and a failure to validate it’s output. This is achieved now by an internal helper R6 class MReader that stashes away incomplete lines and completes it upon re-calling.
fixed reference manual that is generated by CRAN, but previously did not contain the package main functions
Improved description in DESCRIPTION of SystemRequirements
added exported function maxima.isInstalled() that is now used upon package attachment, where a message is signaled to install Maxima, if no installation was found.
added exported function maxima.version() which is now used upon package attachment, where a message is signaled when the installed version is lower than the version with which this package has been tested
Test file tests/testthat/test-engine.R: knitting test page now suppresses Warnings, which are subject of tests/testthat/test-warnings.R

added maxima.engine.format() function that can be used to change the output format of the knitr engine
fixed issue that arises when Maxima takes longer to start (which previously caused the interface to freeze)
added functions to record the version number of Maxima that is being used
renamed package to “rim” to avoid confusion with maxima’s rmaxima
communication is now implemented using sockets and the processing is handles by two nested R6 classes
return type is now a S3 class of type maxima. There are two methods iprint() and oprint() for printing an maxima S3 object: printing the input command and output respectively, including reference labels.
removed external C++ library dependencies (now using sockets for communicating with Maxima)
knitr engine now prints output after each input line, it also prints the input reference label in front of the command

removed dependency from boost (switched to libexecstream)
maxima.get() returns character vector with added attributes for reference labels, format and it’s originating command
fixed Maxima error (message) forwarding to R
implement knitr-engine for maxima using this interface
Implement stop function to end maxima child process for debugging purposes
Handles asksign and similar feedback interruptions
Added interface to maxima’s apropos()-function
Fixed: If command terminates with \$ then this causes a segmentation fault, which kills the R process. The cause being that maxima returns immediately with the next input prompt
added roxygen2 documentation
fixed system.file call inside constructor to work with devtools::load_all()
Added a NEWS.md file to track changes to the package.
Add test files
implemented output display as tex (not yet user-friendly)
added initialization files
added function void loadModule(const std::string &s)
Removed boost::regex linking dependency
fixed pipe stream synchronization
