Adding Multifile API support

[erfemega]

Add multifile API support:

• Detect root files
• Detect related files
• Bundle
• Adding support to Remote reference resolution

Detect root files example of usage

let serviceContent = fs.readFileSync(service, 'utf8'),
      typesContent = fs.readFileSync(types, 'utf8'),
      input = {
        type: 'multiFile',
        specificationVersion: '1.1',
        data: [
          {
            path: '/services.wsdl',
            content: serviceContent
          },
          {
            path: '/types.xsd',
            content: typesContent
          }
        ]
      },
      result = await detectRootFiles(input);

Output:

{
 "result": "true",
 "output": {
   "type": "rootFiles",
   "specification": { // corresponding specification and version info
     "type": "WSDL",
     "version": "1.1"
   },
   "data": [
     {
       "path": "services.wsdl" // corresponding path provided in input as fileName
     },
     ...
   ]
 }
}

Detect related files example of usage:

let service  = fs.readFileSync(servicePath, 'utf8'),
      data = fs.readFileSync(dataPath, 'utf8'),
      input = {
        type: 'multiFile',
        specificationVersion: '1.1',
        rootFiles: [
          {
            path: '/service.wsdl'
          }
        ],
        data: [
          {
            path: '/service.wsdl',
            content: service
          },
          {
            path: '/data.xsd',
            content: data
          }
        ]
      },
      result = await detectRelatedFiles(input);

Output:

{
 "result": "true",
 "output": {
   "type": "relatedFiles",
   "specification": { // corresponding specification and version info
     "type": "WSDL",
     "version": "1.1"
   },
   "data": [
     {
       "rootFile": {
         "path": "service.wsdl" // corresponding path provided in input as fileName
       },
       "relatedFiles": [
         {
           "path": "data.xsd" // corresponding path provided in input
         }
         ...
       ],
       "missingRelatedFiles": [
         {
           "path": "/missingfile.xsd"
         }
       ]
     },
     ...
   ]
 }
}

Bundle files:

let serviceContent = fs.readFileSync(service, 'utf8'),
      typesContent = fs.readFileSync(elements, 'utf8'),
      input = {
        type: 'multiFile',
        specificationVersion: '1.1',
        rootFiles: [
          {
            path: '/service.wsdl'
          }
        ],
        options: { },
        data: [
          {
            path: '/service.wsdl',
            content: serviceContent
          },
          {
            path: '/data.xsd',
            content: typesContent
          }
        ]
      },
      result = await bundle(input);

Output:

{
 "result": "true",
 "output": {
   "type": "bundledContent",
   "specification": { // corresponding specification and version info
     "type": "WSDL",
     "version": "1.1"
   },
   "data": [
     {
       "rootFile": {
         "path": "service.wsdl" // corresponding path provided in input as fileName
       },
       "bundledContent": "<Bundled content of given API Definition>",
       "referenceMap": {}
       
     },
     ...
   ]
 }
