runGUI: run the GUI shiny app for the QCA package
Description
Runs the graphical user interface app based on the shiny package.Details
This function is nothing but a wrapper to the runApp() function in package
shiny.
It locates the gui directory in the path where the QCAGUI package has been
installed, and runs it.
Since version 2.2, the user interface gained an interactive R console in the webpage. Commands are
parsed and evaluated into a dedicated environment, with efforts to capture errors and
warnings. Preliminary tests are encouraging, but users should be aware this is not a
real console and bugs are likely to appear in this stage of development.
