VReqST

Changed the instances of files to validators at all the locations.
On My Validators page, displayed whether it is a private file or not for each validator.
Handled all the cases and made some necessary changed in the Edit Validator page.
On My Projects page, displayed the name of the template validator used for each project.
Added a dropdown for selecting the template validator during the creation of a new project.
Disabled the access to future JSONs without validating the current JSON.
In each project, added a new tab Publish to the existing tabs Write and Read in Custom JSON.
Modified the Write tab by moving the semantics to the left side and handling the buttons.
Changed the Read tab to just view the existing behaviours (Name, Description and Logic).
Implemented Drag and Drop of the behaviours in the Publish tab to create the Custom JSON.
Added the reorder option after drag and drop along with the suitable buttons in Publish tab.
