Edit Function which enter data from register from file

[Iliyan Iliev]

You should complete your function which write data into file. You should make string like this

id,username,password,isAdmin,Badge1|Badge2|etc,
0,pesho,pesho123,1,Admin|Design,

You can see my method inputElementsIntoVector()
It's very similar.

Notes:

• You MUST use vector type
• This function is only part of data layer
• Make this function method from class DATA_LAYER
• DON"T MAKE SPAGETHI CODE
