ctsit/redcap_entity: REDCap Entity

REDCap Entity is a software development library that simplifies the development of REDCap External Modules by providing tools to design, store, manage, enter, view and edit data entities needed by a REDCap Module.

Release 2.1.0 adds a prefix to exposed filters keys to avoid conflicts with reserved REDCap keys. This prevents blank page responses when the PID is not specified in the search.
