add autocompletion of iop filetypes

add a syntax error detection to the vim ide

Make it easier for developers to read the code in the vim ide
by adding a syntax highlight for the iop files :

• Add keywords like ( basic and complex types + the class keyword) @abderrahmaneMustapha
• Detect comments @abderrahmaneMustapha
• Detect TODOS in a coment ] @abderrahmaneMustapha
• highlights data types values ( string, int, unit ) @abderrahmaneMustapha
• highlight iop tags @abderrahmaneMustapha
• highlight classes, class id @theLegend98
• highlight classes names as a type
• highlight parent of a class in cases of inheritance

We need to improve our auto-completion for example

1. if the cursor is in the start of the line the plugin suggest class , enum , struct or a decorator but not string
2. another example is when i have something like this :

class ClassName  {
  ]
.........

lets say the cursor is ] ur plugin need to suggest a string , int , or other basic types , we can also add existing class names to this suggestions because this class name can play the role of type .

indentation inside a class can get messy
