Rename "OutputFormat" folder to "Output" #130
Description
The folder vdisp/src/OutputFormat has a misleading name. Everything in the folder is related to output, but not necessarily its format, thus the name Output would be more fitting for the folder name.
Make sure to check all include() statements at the top of files that include any modules from within this folder and update the path passed into the include() function. Do not forget to do this in the vdisp/test directory modules as well.
