* \brief QueryFactory.h
* \note
* \details contains: a class to produce a query based off of user-entered information
*
* Essentially, this class is used to construct a query based off of user input
* (typically from the command line; if in code directly, the query itself
* could just be instantiated)
*
* In theory, could also be used as the interface to validate incoming datasets
* as belonging to a particular query style
