Add a demo page to showcase JSON schema based dynamic form building using plugin

Lets assume following domain model..

Employee -> 
	firstName String required 100chars max, 1 char min
	lastName string required 100 chars max, 1 char min
	doj date required
	hasLeft boolean
	lastWorkingDay date
	title string required 150 characters max
	emailId - email type - required 250 characters max email validation
	cell phone - number/string masked
	ssn no - number - masked
	aadhar no. - number - masked
	addresses - array of type Address
	trainings - array of type Training

Address ->
	line1 string required 100chars max, 1 char min
	line2 string 100 chars max
	city string required
	pincode string min 5 max 9
	state string required
	country string required

Training ->
	title string required 100 chars
	startDate - date required
	endDate - date
	trainingMasterId - required integer
	grade - 1 char
       Feedback - integer (1 to 5) - to be created using star widget 

Masking is a secondary priority

Latest version of this plugin (0.7.0-alpha.1) brings breaking changes.. it also brings mandatory peer dependency of Material and CDK.. which is little weird 😞

I am re-evaluating my choice of library at the moment..

[dharapvj]

Also.. in the demos which I tried the page continually refreshes losing all the styles in the process..

Either the version I am using is little unstable at the moment OR I am not configuring it well.. Need to analyse it futher

useful editor to edit the json schemas
